Secrets "They" Don't Want You To Know: Vaccines and the Bottom Line for "Big Pharma"
As far as conspiracy theories go, this doesn't even make internal logical sense: pharmaceutical companies make very little money selling vaccines, but they can indeed make a fortune treating measles, polio and other diseases which vaccines can cheaply eradicate. Andrew Wakefield, whose now-discredited "study" started the whole anti-vax nonsense, was proven to have undisclosed financial ties to various pharmaceutical companies; had his BS claims been true, Wakefield would've got very, very rich off them.
Remember, if you must be an anti-vaxxer, make sure you buy up lots of stock shares in pharmaceutical companies first: if you're going to shill for Big Pharma and increase the net amount of human suffering in the world, at least make some money off of it! Jenny McCarthy does.
