The Data In Support of Vaccines are Nothing Like the “Data” That Supposedly Support Evolution

The theory of evolution has damaged science in many ways. It has reduced the progress of science, trapped scientists within an inconsistent framework, and promoted a dogmatic view of science that squelches opposing views. It has also had one other effect: It has reduced the stature of science in the public’s eye. After all, if so many scientists are willing to believe a theory that is opposed by the vast majority of the data, how can you believe anything that scientists say? Many anti-vaccination advocates prey on that perception. They claim that a belief in the safety and efficacy of vaccines is much like a belief in evolution – nothing more than a desire to stay within the “mainstream” of science.

That claim ignores one very important difference between vaccines and evolution: direct, repeatable experiments. Simply put, you cannot put the theory of evolution to the test with an experiment. You can look at data such as fossils, radioactive decay, etc., and then you can INTERPRET those data, but you cannot do any direct experimentation testing the theory. Since your only option is to INTERPRET data, any conclusion that you reach will be very tentative, because interpretation of indirect data is prone to all sorts of problems. Your world view will color the interpretation; the interpretation will be built on many untestable assumptions; and the very data you are using may not even be relevant to the theory. As a result, no matter how careful you are, you may very well be wrong in your conclusion. This is certainly the case when studying the theory of evolution. The data you are studying are indirect, so any conclusion that you reach must be very tentative.

This is definitely not the case when you are studying vaccines (or any other medical procedure), because you can do direct experimentation to determine their safety and efficacy. For example, before a vaccine can be licensed, it must go through several levels of controlled studies. First, it must be tested on animals. A group of animals is given the vaccine, and another group (the control group) is not. They are all then exposed to the germ that causes the disease. If the rate of the disease is significantly lower in the vaccinated animals than in the unvaccinated animals, and if there are no undesirable health effects in the vaccinated animals as compared to the unvaccinated animals, then the vaccine can be tested on human volunteers.

In the first level of human tests, a small group (usually less than 100) of volunteers is given the vaccine. If, over the next few months, there are no adverse effects noted in the small group compared to the population at large, then the vaccine can move on to the next level of clinical testing. In that level, a larger group (usually several hundred volunteers) is given the vaccine, and they are followed for up to two years. The rate of the disease in the testing group is compared to the rate for the nation as a whole. In addition, the rates of several health maladies in the testing group are compared to the rates of those maladies for the nation as a whole. If the rate of the disease is lower in the testing group as compared to the nation as a whole, and if the rates of the health maladies are no higher than the corresponding rates of the nation as a whole, then the vaccine is allowed to go to the final level of testing.

In the final level of testing, a huge group (typically several thousand) of volunteers is given the vaccine, and their health is tracked for several years. Once again, the incidence of the disease in the test group is compared to that of the nation as a whole, and the incidence of several health maladies in the test group are also compared to those of the nation as a whole. In order for the vaccine to be licensed, the rate of the disease against which the vaccine works must be significantly lower in the testing group than in the nation as a whole. In addition, the incidence of health maladies in the testing group must be no higher than that of the nation as a whole.

Notice, then, how vaccines are studied. They are put through direct experiments. First, animals are used. Then, humans are used in three separate kinds of direct experiments. The nation as a whole acts as a control group (those who make up the statistics did not get the vaccine), and those who get the vaccine are compared to that control group. The vaccine can only be licensed if the group that gets the vaccine has a lower incidence of the disease and no more health maladies than the control group. This is the basic scientific method.

In addition to all of these studies, follow-up studies are done once the vaccine is being used in the general population. Groups of people who get the vaccine are constantly compared to groups of people who (by choice or religious conviction) do not get the vaccine. In order for the vaccine to continue to be used, the group getting the vaccine must always have a significantly lower incidence of the disease as compared to those who do not get the vaccine, and they must have no greater rates of health maladies than those who do not get the vaccine. These are direct studies. There is no interpretation involved.

Compare this to the theory of evolution. In the study of evolution, there are no direct experiments. You can look at the fossil record, for example, but you must first assume how those fossils were made. Were they the result of slow accumulation over millions of years or fast, catastrophic processes? There seems to be evidence both ways. I think that the preponderance of evidence favors fast, catastrophic processes, but many scientists would disagree with me on that point. As a result, their interpretation of the fossil record will be different than mine, leading them to a completely different conclusion.

When studying vaccines, we need not make such assumptions. We directly compare those who get the vaccines to those who do not. There is no room for interpretation – if the testing group has a lower incidence of the disease than the control group, then the vaccine is effective. If not, the vaccine is not effective. If the testing group has the same (or lower) rates of health maladies as compared to the control, then the vaccine is safe. If not, the vaccine is not safe.

Because the data related to vaccines is direct, the conclusion that the standard vaccines are safe and effective is a solid, scientific conclusion. As a result, the vast majority of scientists, including young-earth creationists, agree that vaccines are safe and effective. For example, one of the leading young-earth creationist groups in the world is Creation Ministries International. On their website, they have posted a very positive discussion on vaccines. Some of their readers were obviously upset by this, and they wrote in to complain. The scientist at Answers in Genesis had very little patience with them. In addition, I work with a wide variety of young-earth scientists who have various degrees in the life sciences. When I speak with them about the anti-vaccination movement, they all shake their heads. They are familiar with the anti-vaccination movement, but they are also familiar with the science behind vaccines. As a result, they are amazed that anyone could believe the anti-vaccination movement.

Now, does the very fact that most young-earth creationists agree that vaccines are safe and effective prove the case? Of course not. However, the point is that if any scientist is willing to buck the “mainstream” of scientific thought, it would be a young-earth creationist. However, the vast majority agree with the scientific mainstream when it comes to vaccinations. Why? Because the data are so clear on the subject.

Probably the best admonition to Christians comes from Creation Ministries International. In their response to anti-vaccination advocates, they state:

But we urge people to always check what they read, especially on the Internet where anyone can publish anything. The vast majority of websites do not have the checks and balances by highly qualified referees as the CMI site tries to apply.

We also remind Christians that CMI is primarily pro-Bible, especially on its teaching that death is the result of sin. Our anti-evolution/millions of years stance is the corollary of this, not the end in itself. By extension, we are not anti-establishment for its own sake. We oppose the ‘establishment’ only where they conflict with the Bible. So we urge Christians to ensure that their stance comes from being pro-Bible, not a knee-jerk anti-establishmentism.

I truly pray that every Christian takes that admonition to heart!

Dr. Wile is not a medical doctor. He is a nuclear chemist. As a result, he does not dispense medical advice. He simply educates the public about scientific issues. Please consult a board-certified medical doctor before making any medical decisions for yourself or your family.

Individuals Who Have Suffered and Even Died Because They Were Not Vaccinated

When you look at disease rates in countries where vaccination rates are low and compare them to disease rates in similar countries where vaccination rates are high, it is clear that many people needlessly suffer and even die because they are not vaccinated (See our article entitled “Small Decision, Large Impact: Why Not Vaccinating Your Child Is Dangerous”). From a medical point of view, such data clearly show that the decision not to vaccinate can lead to terrible tragedy.

However, such raw statistics may not drive home the personal tragedy that results from not being vaccinated. As a result, I want to discuss the personal stories of several people who learned (the hard way) the dangers of not being vaccinated. I pray that their stories will help people realize the risk that they face if they choose not to vaccinate.

Mathilda (last named withheld by request)
I recently received the following from a homeschooling mother. It shows what happens when people believe the lies of the anti-vaccination movement:

“Thank you for your vaccine stance and research! I am a mother who had heard some “horror stories” and was wary of vaccines. As a result, my 3 year-old daughter (now 7) went deaf in one ear due to complications of chickenpox. I have since immunized my younger son (& dear daughter has been immunized against all other known diseases for which vaccines were appropriate)”

The mother (Tammy) hopes that her experience will keep others from believing those same lies.

Christopher Aaron Chinnes
Christopher Aaron Chinnes died of complications due to chickenpox at age 12. He would most likely be alive today if he had been vaccinated against chickenpox. His mother is on a crusade to get every child vaccinated so that no one else has to experience her grief. Read her heart-wrenching story here.

Joseph Patrick Kepferle
Joseph Patrick Kepferle contracted meningococcal meningitis while in college. Had he gotten the vaccine, as was recommended by the college, he would most likely be alive and well today. His parents are on the board of the National Meningitis Association, which urges all students to be vaccinated against this deadly disease. Read about the tragedy here.

Evan Bozof
Evan Bozof was a healthy, 20-year old college student until he contracted meningococcal meningitis at college. He died within a month of contracting the disease. There is a vaccine available, and it costs about $60. The boy’s mother, Lynn Bozof, said, “I am positive if I had known about the vaccine that helps prevent meningococcal meningitis, my son Evan would have been immunized and he would be alive today.” (http://www.sabin.org/news_aug6.htm). Read more about Evan and the dangers of meningitis at college.

Ryan Milley
Ryan Milley had graduated from high school and was getting ready for college when he was killed by Meningococcal Meningitis. His mother, Frankie, says, “Within 48 hours of his death I heard about MENOMUNE, a vaccine that could have saved Ryan’s life. For years our military have been vaccinated against this disease. Yet our children have been left to be mutilated or killed by this disease.” She is the founder of Meningitis angels, an organization that tries to educate people so that they do not have to live through her tragedy. Read her story here.

Amanda
Dr. Dean Blumberg tells the heart-wrenching story of a family that he treated. The family did not vaccinate, and the elder daughter of the family was infected with whooping cough. Although she was able to get over the sickness, she unfortunately gave it to her younger sister, Amanda, who was only two months old. The poor baby coughed so much that she could not get enough oxygen to her brain, and she died. The baby was too young for a vaccination, but had her sister been vaccinated, she would most likely not have gotten the disease and thus not have passed it on to her poor baby sister. Think of the emotional devastation of the family: a lost baby that was infected by her own sister. All of that heartache could have been prevented by a simple vaccination! ¹

Nine innocent children in Philadelphia
Dr. Offit, chief of infectious diseases at Children’s Hospital of Philadelphia, experienced the 1991 measles epidemic in Philadelphia first-hand. During that epidemic, 1,600 children contracted measles and nine of them died. As Offit says, “At the heart of the outbreak in the city was a Baptist church whose members chose not to vaccinate.” Of the nine innocent children who died, seven were from that church. The other two who died were babies who had yet to get their MMR vaccination. Had the church not been anti-vaccination, these nine precious ones would still be alive today. ²

Name Withheld
A previously healthy 11-year old girl died of complications from varicella infection on May 24, 2002 ³. On May 23, 2002, she came to the emergency room with a history of fever, tachypnea, and chicken pox infection that had lasted up to 12 days. The Emergency Room physician recognized the patient was in shock and she was immediately transported to the Pediatric Intensive Care Unit. She was urgently intubated and CPR was initiated. The child died early the next morning. She had not been vaccinated. If she had been vaccinated, she would most likely be alive and well today.

Amanda Worthy
In 1990, Anne Marie Worthy refused the Haemophilus influenzae Type B (Hib) vaccine for her daughter Amanda. Amanda came down with Hib and as a result had epiglottitis, a severe swelling of tissue in the throat that is caused by Hib bacteria. She wound up spending three weeks in intensive care, but she pulled through. Today, she is deaf in one ear and has a learning disability that requires daily medication to stimulate brain cells. Her mother is now a strong advocate of vaccination. Read about Amanda’s tragic story.

John Kach
John Kach was never vaccinated against meningococcal meningitis because the shots were too expensive. In college at age 19, he was infected and went into a coma. He survived, but only after amputation. Read about his ordeal and how he is coping now.

Aaron Chottiner
Just one month before he was scheduled for his MMR vaccine, 11-month old Aaron came home from daycare with red, watery eyes, a cough, and a mild fever. Eventually, he was diagnosed with measles, but not before he had also infected his mother. Although his mother completely recovered, Aaron never did. He is free of measles, but he has a chronic respiratory illness that is a result of the measles infection. He will have to live with that for the rest of his life. Most likely, he caught measles from a child in daycare who was not vaccinated, as several children from that daycare came down with measles. As Becki says, “One person who wasn’t immunized made several babies sick with the disease, and three of them were hospitalized. We have an obligation to consider not only our own children, bit all the children they come into contact with.”⁴

Mary Catherine
Suzzane Walther was concerned about the safety and efficacy of vaccines, so she decided to do more research on vaccinations before giving them to her child. As she was researching, her child, Mary Catherine, contracted the vaccine-preventable Hib virus. Her child survived, but not without suffering first. She is now furious with herself for believing the lies of the anti-vaccination movement. Read her story here.

If you would like to read more stories that bring the dangers of not being vaccinated down to a personal level, visit the The Immunization Action Coalition’s website. They currently have fifty “stories of people who suffered or died from vaccine-preventable diseases.”

Anti-Vaccination Advocates Lie About the Vaccine Adverse Effects Reporting System (VAERS)

The Center for Disease Control (CDC) runs a very important data-collection agency called the “Vaccine Adverse Effects Reporting System,” which is usually called the VAERS. This system serves an incredibly important function. It allows the CDC to monitor the safety of vaccines after they are licensed for use. The importance of this system has already been demonstrated, as it is responsible for the rotavirus vaccine being removed from the standard vaccination schedule after only a year of use. As I discuss in another article ¹, the VAERS was able to show clinical investigators that there was a serious bowel obstruction associated with the rotavirus vaccine in a very small number of cases (1 case for every 11,073 doses of the vaccine). This side effect was too infrequent to be seen in the the clinical trials required for licensure, but the VAERS was able to identify it quickly. As a result, the rotavirus vaccine was pulled from the standard vaccination schedule. What is the VAERS? It is a system by which a medical doctor can report any adverse medical situation that occurs in one of his or her patients shortly after a vaccination. The doctor might not think that the adverse situation is due to the vaccination at all, but the doctor should still report it. When reports of serious medical situations come in, they are investigated by a team of clinical analysts to determine whether or not the situation is possibly related to a vaccination. If the team thinks that there is a possible relationship, further studies are done to determine whether or not any relationship actually exists. If a relationship between a vaccine and a serious medical condition is verified, the use of that vaccine is then questioned. This can lead to a vaccine being pulled from the standard vaccination schedule, as was the case with the rotavirus vaccine.

The VAERS, then, is an important tool used by serious medical scientists to monitor the safety of vaccines. As is the case with most things associated with real medical science, however, anti-vaccination advocates lie about the VAERS in order to try to scare parents. Consider the following quote ²:

“The Federal government VAERS (Vaccine Adverse Events Reporting System) was established by Congress under the National Childhood Vaccine Injury Compensation Act of 1986. It receives about 11,000 reports of serious adverse reactions to vaccinations annually, which include as many as one to two hundred deaths, and several times that number of permanent disabilities.”

Note what this author is saying. He says that the VAERS receives about 11,000 reports of serious adverse reactions to vaccinations annually. However, that is an out-and-out lie. The VAERS does not receive reports of adverse reactions to vaccinations. It receives reports of medical conditions that follow vaccination. These medical conditions may or may not be an adverse reaction to a vaccine. In fact, the vast majority of them are not. However, that is not determined by the doctor who reports to the VAERS nor by the VAERS. Whether or not the medical condition is related to the vaccination is determined by the team of medical scientists who analyze the data as well as the investigators of any follow-up studies that are done.

A medical condition reported to the VAERS, then, is not necessarily an adverse reaction to a vaccination. It could just be something that happened close to the time of vaccination by sheer coincidence. However, anti-vaccination advocates are very happy to ignore that incredibly important distinction. They want to scare you, and a number like 11,000 serious adverse reactions per year does scare, even if it is an out-and-out-lie.

But wait a minute. Can there really be 11,000 serious medical conditions that occur after vaccination by sheer coincidence? Not really. It is difficult to quote the anti-vaccination literature without finding more than one lie in the quote. The author is not only lying about the idea that these conditions are vaccine-related, he is also lying about the number. The CDC produced an analysis ³ of VAERS reports over the eleven-year period from January 1, 1991 to December 31, 2001. During that period, the total number of conditions reported to the VAERS averaged 11,700 per year. However, the vast majority of those conditions were not serious! Most of them included things like mild fever, hypersensitivity at the injection site, rash, etc. According to the report, only 14.2% of the conditions reported were serious. Thus, the real number of serious conditions reported to the VAERS each year is not 11,000. It is roughly one-tenth that, or 1,700 (1,661 annually during the eleven-year period in the study).

Okay. Now that we have sifted through yet another lie and found the truth, let’s ask the correct question. Can there really be 1,700 serious medical conditions that occur each year after vaccination as a result of sheer coincidence? The answer is absolutely yes. After all, millions of vaccinations are given, and thousands of serious medical conditions occur in children every year. By sheer coincidence, then, some of those serious medical conditions will follow vaccination, even though they are not related to it in any way.

The best way to illustrate this us by example. Consider Sudden Infant Death Syndrome, which is usually called SIDS. We know for a fact that children who get the DPT vaccination are actually less likely to die of SIDS than those that do not get the vaccination. Not only do serious studies demonstrate this to be the case, we actually know the biochemical mechanism by which the DPT vaccination protects against SIDS. ⁴ As a result, we know for sure that the DPT vaccine does not cause SIDS. It actually protects a child to some degree from SIDS. Nevertheless, SIDS cases after DPT injection continually get reported to the VAERS every year, despite the fact that we know that the DPT vaccine actually protects against SIDS. Why do the deaths get reported to the VAERS? Sheer coincidence. Let’s look at some numbers so that you can see how such coincidences can occur.

Each year, there are 1.39 SIDS deaths per 1,000 children in the United States. Each year, there are 4.1 million births in the United States.⁵ Since there are 1.39 SIDS deaths per 1,000 live births each year and 4.1 million births annually, you can work out the numbers to find that there are 15.6 SIDS deaths each day. Now, if all of these children get the DPT, there would need to be 12.3 million doses of the DPT, since each child needs three doses. This works out to 33,698 doses each day. What does this tell us? This tells us that on any given day, the fraction of children under one year of age that are getting the DPT is 33,698 / 4,100,000, or 0.00822.

Now, if there are 15.6 SIDS deaths each day, and the fraction of all children less than one year old getting the DPT is 0.00822, then 0.00822 x 15.6 = 0.1282 children will die of SIDS on the same day as their DPT shot by coincidence alone. This works out to 46.8 deaths each year. Thus, by sheer coincidence, there will be 46.8 SIDS deaths that occur on the same day that the child gets the shot. If all doctors report this to the VAERS, then the VAERS will have 46-47 SIDS deaths each year, even though the DPT vaccine actually protects against SIDS!

As you can see, then, simply discussing what has been reported to the VAERS is meaningless. There is no way to separate the coincidental deaths (and other medical conditions) from the ones that are caused by the vaccine. To do that, it takes detailed studies. Sometimes, those studied find a link (as was the case with the rotavirus vaccine), but most of the time, they do not.

The sad part of this tale is that the CDC makes it very clear in all of its publications that a condition reported to the VAERS is not necessarily vaccine-related. For example, here is what the CDC has on its opening page to the web version of the VAERS ⁶:

“In some media reports and on some web sites on the Internet, VAERS reports are presented as verified cases of vaccine deaths and injuries. Statements such as these misrepresent the nature of the VAERS surveillance system.” (Emphasis theirs)

In order to reach the data, you must click a link that says you have read and understood this statement. Thus, the anti-vaccination people who report VAERS conditions as vaccine-related are either lying about what they have read, or they are parroting others and have not checked out the facts for themselves. Either way, it should give you some indication of how seriously you should take such writings!

Vaccines are THOROUGHLY Tested, Both Before and After Licensure

Anti-vaccination advocates often prey on the public’s lack of knowledge of medical science and the medical literature. This is never more apparent than when the anti-vaccination advocates claim that vaccines are not well-tested before they are used. For example, many anti-vaccination advocates present the following quote:¹

“There has never been a single vaccine in this country that has ever been submitted to a controlled scientific study. They never took a group of 100 people who were candidates for a vaccine, gave 50 of them a vaccine and left the other 50 alone, and measured the outcome. And since that has never been done, that means if you want to be kind, you will call vaccines an unproven remedy. If you want to be accurate, you’ll call the people who give vaccines quacks.” –Robert S. Mendelsohn, M.D.

Now I honestly do not think that Dr. Mendelsohn actually said this, because I cannot imagine that a medical doctor could be this ignorant of his own field. Also, I have never seen a reference for this quote to something that Dr. Mendelsohn actually wrote. However, the point is clear. According to anti-vaccination advocates, vaccines are not tested before they are given to the general population.

Of course, as is the case with most of the claims made by anti-vaccination advocates, this could not be further from the truth! Before a vaccine can be licensed, it must go through several levels of controlled studies. First, it must be tested on animals. A group of animals is given the vaccine, and another group (the control group) is not. They are all then exposed to the germ that causes the disease. If the rate of the disease is significantly lower in the vaccinated animals than in the unvaccinated animals, and if there are no undesirable health effects in the vaccinated animals as compared to the unvaccinated animals, then the vaccine can be tested on human volunteers.

In the first level of human tests, a small group (usually less than 100) of volunteers are given the vaccine. If, over the next few months, there are no adverse effects noted in the small group compared to the population at large, then the vaccine can move on to the next level of clinical testing. In that level, a larger group (usually several hundred volunteers) is given the vaccine, and they are followed for up to two years. The rate of the disease in the testing group is compared to the rate for the nation as a whole. In addition, the rates of several health maladies in the testing group are compared to the rates of those maladies for the nation as a whole. If the rate of the disease is lower in the testing group as compared to the nation as a whole, and if the rates of the health maladies are no higher than the corresponding rates of the nation as a whole, then the vaccine is allowed to go to the final level of testing.

An example from history might help. The largest clinical study in the history of the United States was done on a vaccine. In 1954, the trial of the Salk polio vaccine was performed on 1.8 million children ². This trial was a double-blind, placebo-controlled study. In other words, half of the children got the vaccine, and the other half got the placebo. Until the end of the study, no one knew which children were which. In the end, the data indicated that the children who got the vaccine were significantly less likely to contract polio than those who got the placebo. In addition, the number of polio-unrelated illnesses were the same in the group of children who got the vaccine as compared to those who got the placebo. Thus, the vaccine was considered both safe and effective, and it was licensed for use.

In order to be licensed, every vaccine must go through not one, but at least two such trials, and that is after the vaccine has been tested on animals and tested on a small group of individuals mainly to judge its safety. Some vaccines do not make it. For example, doctors have tried to develop a vaccine against Respiratory Syncytial Virus (RSV) for years. It is one of the biggest killers of infants and young children in the U.S. There have been vaccines made, but they have never been approved for use, because the studies done on them demonstrate that they are not safe enough or effective enough to be considered a reliable medicine ^3,4.

That’s not even the end of the story. Not only must a vaccine pass through one level of animal study and three levels of human studies in order to be licensed, it is then continually monitored through the Vaccine Adverse Effects Reporting System (VAERS). This system is specifically designed to look for problems with vaccines, no matter how rare. For example, in 1999, the VAERS logged 15 serious bowel obstructions that occurred shortly after the rotavirus vaccine was administered. This frequency was quite low, since 1.5 MILLION doses of the vaccine had been given that year. Nevertheless, studies were done to see if those bowel obstructions were, in fact, related to the vaccine.

Several studies were done ⁵, and the most thorough one demonstrated that there was a slightly elevated risk of serious bowel obstructions (one case in every 11,073 children vaccinated) for those who received the vaccine. Even though the risk is rare, the severity of the bowel obstruction combined with the low mortality of rotavirus in the United States led to the decision to pull the rotavirus vaccine from the standard vaccination schedule.

So you can see that vaccines, are rigorously tested before they are licensed for use, and then once they are licensed, they are continually monitored for safety. As the American Academy of Pediatrics says, “…vaccines are one of the safest forms of medicine ever developed.”⁶ The members of this academy ought to know. They have all spent several years studying medicine at the college and post-college level, and they have devoted their careers specifically to the health of children. To ignore their expertise would be quite foolish, especially in light of the fact that those encouraging you to do so must lie in order to make their case!

Reliable Sources of Vaccine Information

When investigating medical issues, you must be very careful what you read on the internet. Although the internet provides wonderful access to a wealth of information, it also provides access to a lot of nonsense as well. This nonsense seems to be most evident when the information is related to health. Thus, you must view the health information you read on the internet with a lot of skepticism. Check references, see what knowledgeable people say about the source, etc. etc. Lots of smart, educated people have been fooled by nonsense on the internet. Don’t allow yourself to be one of those people!

Please find below a list of websites that I find to be very reliable when it comes to vaccinations. If you are reading the nonsense put out by the anti-vaccination advocates, please at least balance your reading by investigating theses sources!

A Small List of the Lies Told by the Anti-Vaccination Movement

One of the first things that struck me when I began reading the anti-vaccination literature is the large amount of deceit that is employed by anti-vaccination advocates. To combat that deceit, I have compiled a list of the many lies told by the anti-vaccination advocates.

The low rate of childhood diseases are the result of better sanitation and living conditions, not vaccines.
When outbreaks occur, the vaccinated children are the most susceptible to infection.
Vaccines are not adequately tested.
The Pharmaceutical Companies Control the Scientific Research on Medicines.
Vaccines are recommended by doctors because of the financial interests of the pharmaceutical companies.
Vaccines cause Autism.
Vaccines cause Sudden Infant Death Syndrome.
Vaccines cause Multiple Sclerosis.
Vaccines contain fetal tissue.
Vaccines suppress the immune system.
Serious conditions reported to the Vaccine Adverse Effects Reporting System (VAERS) are vaccine-related.

Anti-Vaccination Advocates Use Statistics to Lie

One common statement used in anti-vaccination literature is that when outbreaks of vaccine-preventable diseases occur, the majority of those infected turn out to be vaccinated children. ¹ According to the anti-vaccination advocates, this shows that vaccines are not at all effective at preventing the disease. The problem is that the statistic quoted actually demonstrates exactly the opposite. You see, the problem with the statistic as quoted by the anti-vaccination advocates is that the vast majority of children are vaccinated. Thus, even if only a tiny percentage of vaccinated children get the disease, their numbers will be larger than the number of unvaccinated children who get the disease.

The best way to illustrate this is to think of an example. Suppose a measles outbreak occurs in a school that has a population of 1,000. About 98% of those students (980) will be vaccinated. That leaves 20 that are not vaccinated. Now, suppose that only 2% of the vaccinated population contracts measles. That means about 20 vaccinated students will get the disease. Next, suppose that 90% of the unvaccinated children contract measles. That means 18 of the unvaccinated students will get the disease. Thus, of those who got the disease, 53% were vaccinated, and 47% were not. Does this mean that the vaccines did not work? Quite the opposite! While only a tiny minority of the vaccinated students got the disease, the vast majority of the unvaccinated students got the disease. Being vaccinated made you only 2% likely to get the disease, while not being vaccinated made you 90% likely to get the disease! Clearly, then, the vaccine was quite effective, as vaccinated students were 45 times less likely to be infected than unvaccinated students.

When comparing one group to another, then, you must make sure to take into account that one population might be greater in number than the other. Anyone with a modicum of training in research or statistics know this. Thus, in the medical literature, statistics are always reported in this way. If you look at studies that have been done on measles outbreaks, for example, you will find that the research indicates that vaccinated children are up to 35 times less likely to catch measles than unvaccinated children.² This is the proper way to report such a statistic.

The question is, since the statistics are always discussed properly in the medical journals, why do anti-vaccination advocates misquote them in their literature? They must look at the studies, or they could not get the numbers. Why, then, do they ignore the proper way to quote the statistic and instead use a deceptive way? I think that the answer is obvious: quoting the statistic the proper way will hurt their cause, while quoting them in a deceptive manner will help fool the general public into accepting their ideas.

Vaccines DO NOT Suppress the Immune System

If a parent follows the suggested vaccination schedule ¹, it might seem to the parent that the child is getting am inordinately large number of shots. Many anti-vaccination advocates prey on the fact that most parents are not informed enough to know what is “too much” when it comes to medicine, and they say that this large number of vaccines “overwhelms” the baby’s immune system. Of course, as is the case with most assertions in the anti-vaccination camp, this assertion does not stand up to the data.

Probably the most direct study on this comes from Paul A. Offit and others ². The data analyzed by these authors indicate the following:

Newborns are capable of mounting an immune response at birth. This goes counter to what some anti-vaccination advocates claim, but is nevertheless supported by the data. Of course, any Christian should immediately realize that this is the case. God would certainly design an immune system that was able to respond the moment a baby left the protection of his or her mother’s womb. Anything less would simply be shoddy workmanship!
Mild illness at the time of vaccination does not affect the level of antibodies produced by vaccination. Many who are fooled by the anti-vaccination advocates don’t even realize that we can chemically measure a body’s immune response to a vaccine (or to an infection) by actually measuring the level of antibodies produced in the blood. These antibodies are so well- characterized that we can actually determine which antibody fights which disease. Even though a child might be mildly sick (and thus his or her immune system is fighting off an infection), the child’s immune system makes the same level of antibodies in response to a vaccine as it would if the child were not at all sick. This indicates that God’s wonderfully designed immune system is not easily “overwhelmed!”
When comparing children who are given just one vaccine to children who are given several, there is no difference between the level of antibodies produced. In other words, multiple vaccines do not “fight” each other for attention from the immune system. Whether a child gets one vaccination or several, the level of immune response is the same for each disease. If multiple vaccines “overwhelmed” a child’s immune system, you would see the immune response for each disease decrease as the number of vaccinations increase. This is simply not the case.

Another important study comes from Otto and others ³. This study investigated 496 vaccinated and unvaccinated children, comparing the health of the vaccinated children to that of the unvaccinated children. It found that children who received immunizations against diphtheria, pertussis, tetanus, Hib, and polio within the first 3 months of life had fewer infections than those who did not. Surprisingly enough, even the rates of infections unrelated to the vaccines were lower in the vaccinated group than in the unvaccinated group. Now, if vaccines really did “overwhelm” these babies’ immune systems, we would see the vaccinated group have a higher rate of infections as compared to the unvaccinated group. Instead, we see precisely the opposite, indicating that vaccines do not overwhelm an infant’s immune system.

Vaccines Actually Protect Against Sudden Infant Death Syndrome (SIDS)

For quite some time now, anti-vaccination advocates have tried to link vaccination to Sudden Infant Death syndrome (SIDS). In her book, Vaccination: 100 Years of Orthodox Research shows that Vaccines Represent a Medical Assault on the Immune System, Dr. Viera Scheibner, Ph.D., makes the outlandish claim that when the pertussis vaccination age was moved from 3 months old to 2 years old in Japan (1975), the phenomenon of SIDS (which she calls “cot death”) vanished. Here are a couple of quotes from her book:

“In 1975 Japan raised the minimum vaccination age to two years; this was followed by the virtual disappearance of cot death and infantile convulsions.”¹

“The most important lesson from the Japanese experience is that when the vaccination age was moved to two years, the entity of cot death disappeared.”²

These claims are absolutely false, but they have been repeated over and over again by anti-vaccination advocates ³.

How do we know that they are false? Because a study ⁴ was done on the autopsy records of infants (aged 1 week to 1 year old) who died in the Tokyo area. This study found that the number of SIDS cases rose continually from 1975 through 1993, the last year that the study considered. In fact, from 1979 to 1993, the number of SIDS cases in the Tokyo region increased by more than a factor of 12 ⁵! Clearly, then, SIDS did not disappear from Japan once the vaccination age was raised. In fact, it increased considerably.

Why did it increase considerably? Most likely, it was because the number of forensic pathologists who began recognizing the phenomenon of SIDS increased, not because the actual rate of SIDS increased. In Japan, an unexpected death is identified by the broad term “Sudden Unexpected Death” (SUD). From 1974 through 1993, the SUD rate for infants in the Tokyo area was shaky, but fairly steady, averaging about 30 cases per year ⁶. Thus, the number of infants dying unexpectedly was fairly constant. However, the number of those cases recognized as SIDS rose significantly during the same time period. Most likely, then, it was the diagnosis of SIDS that increased, not the actual rate of SIDS.

The point, however, is quite clear. The SIDS rate in Japan either increased or stayed the same after the vaccination age was raised. It did not lower, much less disappear. Thus, the statement that Dr. Scheibner makes in her book is a lie, and that lie has been repeated over and over again. How in the world could Dr. Scheibner make such an outrageous claim and be believed? Because she referenced her claim to two studies ^7-8, and those who repeat her claim have obviously not checked those references.

If you bother to check her references, you will see that neither of them make any claim regarding the number of SIDS cases in Japan. Instead, they reference the number of claims made to Japan’s vaccine injury compensation program. Much like the United States’ vaccine injury compensation program, Japan offers a program whereby people who think that their child has been injured by a vaccine can apply for compensation. Their claim is reviewed, and if there seems to be any plausible link to the vaccine, the claim is paid. The two articles that Dr. Scheibner references say that the number of SIDS claims to the vaccination compensation program declined to zero once the vaccination age was raised to 2 years. Of course, that would logically have to happen, since SIDS is defined as occurring in children age 1 year or younger. Since no one of that age could get the vaccine anymore, it would be impossible for someone to make a SIDS claim to the vaccine injury compensation program!

So you see that one of the most popular claims made by anti-vaccination advocates is (as usual) untrue, and it has survived only because people who read the claim do not bother to check the references! As is the case with many anti-vaccination claims, a quick check of the medical literature simply destroys the claim entirely.

Not only does the supposed “demonstration” of a link between SIDS and pertussis vaccination in Japan not stand up to scrutiny, a cursory review of the medical literature provides many detailed studies that show that the rate of SIDS amongst unvaccinated children is actually higher than the rate of SIDS amongst vaccinated children! For example, Hoffman and others ⁹ studied SIDS victims using data from the National Institute of Child Health and Human Development. In their study, they compared 757 SIDS cases to 1,514 living control children. The control children were matched to the SIDS cases based on age, race, and low birth weight. According to their results, the living children were 1.3 times more likely to have been immunized compared to the children who died of SIDS. In other words, according to this study, if a child was not vaccinated, he or she was more likely to die of SIDS than if the child were vaccinated!

Although that might sound like a surprising conclusion if you have been reading the anti-vaccination literature, you will find that it is the common conclusion in the medical literature. For example, another study by Walker and others ¹⁰ focused on healthy babies with birth weights greater than 5.5 pounds. For these children, unvaccinated children were 6.5 times more likely to die of SIDS than were vaccinated children.

Why does vaccination actually provide a protective effect against SIDS? According to a biochemical study by Essery and others ¹¹, it is most likely due to the fact that the DPT vaccine produces antibodies that are cross-reactive to staphylococcal toxins, which are found in many SIDS cases. In other words, the study found that the antibodies produced by the DPT vaccine are able to fight the toxins produced in staph infections! Thus, the DPT vaccine not only protects the infant from diphtheria, pertussis, and tetanus, it also offers some protection against SIDS (or at least staph infection)!

So once again we see that the medical literature not only invalidates the claims of anti-vaccination advocates, it actually indicates that by opposing the DPT vaccine, anti-vaccination advocates are actually increasing the incidence of SIDS (along with the incidence of pertussis, diphtheria, and tetanus). This serves once again to illustrate the danger of listening to the anti-vaccination movement.

Vaccines are Incredibly Effective at Preventing Disease

Dr. Lewis Thomas, in his book, Lives of a Cell: Notes of a Biology Watcher, says that the best kind of medical technology is, “…the kind that is so effective that it seems to attract the least public notice; it has come to be taken for granted. This is the genuinely decisive technology of modern medicine, exemplified best by the modern methods for immunization against diphtheria, pertussis, and the childhood virus diseases.”¹ Indeed, over the years, vaccines have become so effective at eliminating disease that they have become taken for granted. So much so that there is a growing movement trying to claim that vaccines do not even help to prevent disease. Nothing could be further from the truth! Vaccines have saved the lives of countless children and adults over the years, and anyone who truly cares for children cannot ignore this rock-solid fact.

There are three main ways that we want to demonstrate the efficacy of vaccines. First, we want to show you the historical data that demonstrate how disease rates fell dramatically as a result of mass immunization. Second, we want to discuss some of the detailed, controlled studies that demonstrate that people are significantly less likely to be infected by a disease against which they have been vaccinated as compared to those who have not been vaccinated. Finally, we want to discuss the devastation that occurs when vaccination rates drop in a population.

Let’s start with the historical data. Below, you will find two graphs showing you the polio and measles rates in the United States from 1944 to 2001:²

There are several important things to notice regarding these graphs. First, notice that in the case of polio, disease rate rose in a shaky but steady fashion from 1944 to 1952. Then, there was a slight (34%) decrease in the disease rate from 1953 to 1955. However, from 1955 to 1957, there was a dramatic decrease (80%) in the disease rate. What explains these drops in disease rate? Well, notice that the first polio vaccine was licensed in 1955. The dramatic decrease in disease rates, then, came right after the polio vaccine was licensed. What about the smaller decrease from 1953 to 1955? Well, Salk developed his vaccine in 1952 and began testing it. For example, in 1954, the Salk vaccine was tested in a double-blind study of 1.8 million children ³. Thus, the benefits of the vaccine are apparent even in the testing phase!

Now look at the graph for measles. Once again, the story is similar. There is not nearly as much of a rise in the measles rate in the early years (1944-1958), but the disease rate follows the typical shaky pattern of epidemic cycles that is often seen in infectious disease rates. However, once again, there is slight decrease in the disease rate just prior to the licensing of the vaccine (during the testing phase), and then a dramatic decrease in the disease rate after the licensing of the vaccine.

Do these graphs demonstrate conclusively that the polio and measles vaccines stopped these dreaded diseases? Of course not. After all, this could all be explained by an amazing coincidence. Perhaps something else stopped each of these diseases, and that “something” just happened to occur during the testing and licensing phases of the vaccine. However, it does add some evidence to the pile. If you truly want to believe that vaccines are not effective, you have to believe in a couple of amazing coincidences in order to explain this data. Of course, this is not the only data available. We can look at other diseases whose infection rates dropped dramatically after the vaccine was introduced. Thus, the number of coincidences in which you must believe (if you think that vaccines are not effective) just keeps increasing!

There is one other very important thing to note from the graphs. Anti-vaccination advocates often try to explain the dramatic decrease in vaccine-preventable diseases in terms of increased sanitation. They say that these disease rates are so low because we have developed better sanitary practices over the years. However, these graphs show that this is just not true. After all, the polio disease rates decreased dramatically in the late 1950s. However, the measles rates did not decrease dramatically for another 10 years. If good sanitary practices were responsible for the drop in disease rates, you should see the disease rates fall roughly at the same time. That’s just not the case. The disease rates fell only when vaccines were tested and then approved. Also, note the short time over which the disease rates fell so dramatically. Do sanitation practices change so quickly that they completely “clean up” a country in a matter of a few years? Definitely not! Improved sanitation just does not explain the data.

In fact, most medical historians blame increased sanitation for the rise in polio from 1944 to 1952. When sanitary practices were rather poor, people were regularly exposed to small amounts of the polio virus, usually when they were babies and therefore had the extra protection given to them by the antibodies they received through their mothers’ milk. Their immune systems were able to conquer the weak exposure to the virus with the help of their mothers’ antibodies, and thus they became immune. As a result, the poor sanitation was actually acting like a “dirty” vaccine! As sanitary practices improved, fewer people were exposed to small amounts of the virus as infants. As a result, when they were exposed to concentrated amounts of the virus (from a person who already had the disease, for example), they would succumb to the disease ⁴. Note that this makes sense in the light of the data, because the rise in the polio rate occurred slowly, which is what you expect when sanitation is playing a role.

Although these graphs are very effective illustrations of the power of vaccines, as we stated before, they are not definitive evidence. After all, coincidences could explain the graphs. By far, the best evidence of how effective vaccines are comes from controlled studies. In these studies, vaccinated people are compared directly to unvaccinated people, and the results are astounding.

For example, Feikin and others studied all measles and pertussis cases among children (age 3-18) in Colorado from 1987 to 1988 ⁵. When they compared the vaccinated children to the unvaccinated children, they found that vaccinated children were 22.2 times less likely to contract measles than were the unvaccinated children. In the same way, vaccinated children were 5.9 times less likely to contract pertussis than were unvaccinated children. In other words, according to this study, if you do not vaccinate your children, you have increased their risk of getting measles by 2,220%, and you have increased their risk of getting pertussis by 590%!

Another finding from this study is that schools in which outbreaks occur have 2.9 times the percentage of unvaccinated students as do schools in which outbreaks do not occur. Thus, this study tells us that those who do not vaccinate their children are not only putting their own children in danger, but they are also putting other people’s children in danger, because the larger the number of unvaccinated children in a group setting, the more likely an outbreak is to occur.

Another study by Salmon and others was even more comprehensive but focused only on measles. They studied measles cases over seven years (1985-1992) using the Center for Disease Control’s Measles Surveillance System ⁶. In their study, they found that vaccinated children (ages 5-19) were 35 times less likely to contract measles than were unvaccinated children. Another important result of their study was that the general measles outbreak that was seen in 1991 (note the small bump at 1991 in the measles graph above) actually started a year earlier among the unvaccinated population. In other words, that outbreak was most likely started by the unvaccinated population! This is another example of parents that do not vaccinate actually putting everyone’s children at risk.

These kinds of studies are done on all vaccines, and the results are just as stunning. In a double- blind, placebo-controlled trial of the flu vaccine, for example, 1,602 children were given a flu vaccine or placebo. Vaccinated children were 13.6 times less likely to catch the flu than those who got the placebo ⁷. That study was expanded to a second year for 1,358 of the children and, in addition, 4,561 adults were added to the study. Once again, those who received the flu vaccine were many times less likely to get flu than those who received the placebo ⁸. Even in the elderly, the flu vaccine is very effective at preventing illness. According to a meta-analysis done on flu-related data in seniors, the flu vaccine reduced mortality rates in people 65 years and older by 50%⁹.

We could go on and on, but the results are quite clear. When vaccinated people are compared to unvaccinated people, the vaccinated ones are significantly less likely to contract the disease than the unvaccinated ones. Thus, controlled studies clearly show that vaccines are quite effective.

A particularly sad way of illustrating the effectiveness of vaccines is to see what happens when vaccination rates in a population are low. Consider, for example, the following graphs of pertussis rates in the United Kingdom ¹⁰:

The graph on the left shows the number of pertussis cases in the UK per year along with the number of pertussis deaths per year (multiplied by 60 so that you can see them on the graph) from 1940-1997. Notice that the disease rate is steady but shaky (as is typical for infectious diseases) until mass immunization begins. As vaccination becomes standard practice, the disease rate decreases.

Now look at the graph on the right. This graph contains the same data (pertussis cases and pertussis deaths – this time multiplied by 700) along with the pertussis vaccination rate from 1966 to 1997. Notice what happened in 1972-1973. The vaccination rate began to decline. This was caused primarily by anti-vaccination advocates who made claims that the pertussis vaccine was linked to devastating side effects such as SIDS. (Detailed, controlled studies show that the DPT vaccine actually lowers a child’s risk of SIDS ^11-13). Notice what happened as the vaccination rate went down – the disease rate went up. This kind of data is nearly impossible to explain if you think that vaccines are not effective. Clearly there was no appreciable difference in sanitation, nutrition, etc. during the1970’s. Nevertheless, that period saw an increase in the number of pertussis cases, and it coincides perfectly with a lowering of the vaccination rate. Then, once the vaccination rate increased again, the disease rate decreased in kind.

While looking at graphs like the one above is very instructive, it is important to note that these data are more than just numbers. They represent innocent children who suffered (and sometimes died) because their parents (or others who were in charge) were fooled by anti-vaccination advocates. The death of any child is tragic, but it is doubly so when it could have easily been prevented through vaccination. If you would like to learn more about the ravages induced on innocent children by the anti-vaccination movement, please see our discussion entitled, Small Decision, Large Impact: Why Not Vaccinating Your Child Is Dangerous or Individuals Who Have Suffered or Died Because They Were Not Vaccinated.

We need to make one more point before we finish this discussion. Anti-vaccination advocates are adept at coloring the facts to suit their agenda (see, for example, Anti-Vaccination Advocates Use Statistics to Lie). Often, anti- vaccination advocates quote death rates from disease and state that the death rates due to diseases like pertussis were declining long before the vaccine was introduced, and this shows that the vaccine is not necessary in combating the disease. However, as is typical, the anti-vaccine advocates who make such statements are either showing their ignorance of medicine or willfully lying.

Even a first-year medical student knows that you cannot track a disease with its death rate. This is because modern medicine learns how to treat the symptoms of a disease before it learns how to treat the disease itself. As a result, the death rate from a disease regularly decreases once the disease has been characterized, even though the number of people catching the disease is constant or increasing. You can see that from the left-hand figure above. From 1940 to 1953, the average pertussis rate in the UK stayed rather steady, while the death rate dropped quickly. This is simply because doctors were treating the symptoms of the disease well, allowing those who contracted it to live longer.

To properly track the prevalence of a disease, then, you must look at the disease rate, not the death rate. This is important for two reasons. First, the disease rate tells you the prevalence of the disease itself, and it is not affected by the ability of doctors to treat the symptoms of the disease. Second, by monitoring only the death rate, you are ignoring the devastating long-term health consequences (deafness, blindness, paralysis, etc.) that accompanies many cases of childhood disease. Many of those who actually survive diseases such as pertussis are faced with a life-long disability that resulted from contracting the disease. These children are not accounted for in a study of the death rate. Thus, the disease rate is the important indicator when tracking the prevalence of a disease, and as the data clearly show, when the vaccination rate increases, the disease rate decreases, and when the vaccination rate decreases, the disease rate increases!

The bottom line is quite simple: Whether you look at disease rates over time or detailed, controlled, scientific studies, vaccines are incredibly effective at preventing disease. There is just no other way to explain the data.
