Polio was not wiped out by enhanced sanitary conditions. People who weren't alive at the time (me included) have no idea how relieved our nation was by the development of the vaccine. Both my mother and mother-in-law cannot swim to this day as a result of the polio epidemic. Slashdotters should like that Salk was open source: "Who owns this patent? No one. Could you patent the sun?" -- Salk
But what's worse than the armchair biologist arguing against vaccines? Vaccines only work when a certain number of the population stays vaccinated. It's the reason why here in Pennsylvania, it was never a threat that the amish community didn't vaccinate. But now with people arguing against them because they "know better," a portion of the non-amish community is refusing to vaccinate.
Why should i care? Because vaccination is not about saving one person, ten people, etc. Vaccination is for preventing an outbreak, which if one occurred, could contain a mutated form of the disease which could kill those who ARE vaccinated. Think in terms of second hand smoke, and you'll understand why this outrages me.
The fraudulent link between autism and vaccination is null and void, retracted by the medical community and the paper that published it. But my kids are in danger, still, as a result of people getting spooked by the vaccination boogie man.
