Here's a summary of their beliefs:
Antivaccine idiot: Mercury in vaccines cause autism.
Scientist: There is no evidence of that.
Antivaccine idiot: Your wrong Jenny McCarthy said so.
Scientist: Ok we'll take it out. Look kids are still getting autism.
Antivaccine idiot: Did we say mercury? We meant it was the MMR vaccine.
Scientist: There is no evidence of that.
Antivaccine idiot: Your wrong Jenny McCarthy said so.
