The anti-vaccine movement tries to portray itself as scrappy grassroots outsiders standing up to Big Pharma and Big Government, but it's nothing of the kind, finds a recent Washington Post exposé.The National Vaccine Information Center, which claims to be the largest "awareness" non-profit opposing vaccines, actually gets almost half of its funding from corporations. And their largest corporate benefactor is the osteopath Joe Mercola, head of a $100 million empire that sells alternatives to medicine for nearly everything. And who funds lots of groups opposed to science, from medicine to food.
