Anti-vaccinationists have made a wide range of claims about the dangers of vaccines. In spite of the fact that they have generally had neither data nor a plausible mechanism for the claimed effect, several of their claims have been investigated by researchers.
As it turns out, the anti-vaccinationists are remarkably consistent. Time and time again, they are shown to be wrong. I’m not sure how many times a group needs to be wrong before people stop seeing them as credible. Perhaps people need to be reminded of how many times this group has been wrong?
So there are some reminders.
