Carrey, and even moreso his girlfriend Jenny McCarthy, are the celebrity faces of America’s growing anti-vaccination movement, which claims there’s a connection between childhood vaccinations and autism despite there being absolutely no evidence for it. The publicity they get opens the door for conmen selling ineffective, and often dangerous, autism treatments. It also leads worried parents to opt out of getting their children jabs, which not only puts their offspring at risk but also those of others. Amy Wallace took a look at the problem for Wired. As with anyone who shows up pseudo-science these days she’s already received threats and been the victim of half arsed character assassination attempts.

I’d call for a boycott of Carrey’s films, but he’s pretty much guaranteed it already by appearing in such total crap. The Grinch wants to kill your children. Pass it on.
