The problem I have with the debate is that if if 100% of vaccines are 100% safe, the pro-vaccine people are constantly arguing against getting vaccines. Just look at the links in the summary. They misrepresent and outright lie about what McCarthy says. They will quote her, and then repeat that she said something she didn't. They will try to change the subject, and they accuser her of moving the goal posts. They are constantly using ad hominem attacks. Basically they are using all of the tactics that a person who is lying would use to support their position.
Heck even the huge Wakefield thing was handled like someone who was trying to cover up bad behavior. Wakefield declares a link between Autism and MMR. He recommends getting the three shots seperatly. What is the pro-vaccine response? To tell people they are stupid murderers and that asking for three seperate shots is a crime against humanity. So, how many people just didn't vaccinate their kids because the pro-vaccine movement told people that they can't get the shots seperately?
If you want to blame someone for a reduction in vaccinations, far more of the blame should be set at the feet of the AAP, CDC, pedeatricians and all of the people on sites like this that constantly take a subject that they are mostly right about, and implicitly tell the public that they are lying.
It is like my wife coming home and finding a womans jacket that does not belong to her. If I just tell her, "Yeah, Ann came by today and we went to lunch.", there is no problem. If I tell her that no one has been to the house, there is a problem. Lying, perticularly in blatently obvious ways, only weakens your position.
