Here is a video of a some of congressmen, especially Rep. Dan Burton (R-Ind.) and Rep. Dennis Kucinich (D-Ohio.) shamelessly repeating rumors about the dangers of vaccines that have been thorough debunked, including fearmongering about mercury in vaccines and giving airtime to conspiracy theorists who think the Centers for Disease Control and Prevention are covering up links to autism.
And here's a picture of a baby who died because a lot of people in her area didn't get vaccinated. That (along with some aspects of the modern form of the vaccine) reduced herd immunity which made babies too young to be vaccinated vulnerable to diseases that should already have been wiped out if people would just stick their kids with needles already!
