This quote seems to be making the rounds on facebook right now:
Saying that your vaccinated child is at risk of disease because of my un-vaccinated child is like saying I have to take birth control pills so YOU won’t get pregnant.
Of course, this is nonsense on two levels. First, it is a bad analogy, because pregnancy isn’t contagious. You can’t “catch” pregnancy from a person who is pregnant, but you most certainly can catch vaccine-preventable diseases from those who have them.
Second, unvaccinated children most certainly can spread disease to vaccinated children. For example, in 2005 an unvaccinated teen went to Romania on a missions trip and brought measles back to her church. 34 people in the church were infected, 2 of which were vaccinated. One of the 34 required six days of ventilator support in order to survive.
If you have been fooled by those who use misinformation to try to keep you from vaccinating, please learn the scientific data behind the safety and efficacy of vaccines.
