John McCain, man of science:
“At a town hall meeting Friday in Texas, Sen. John McCain, R-Ariz., declared that “there’s strong evidence” that thimerosal, a mercury-based preservative that was once in many childhood vaccines, is responsible for the increased diagnoses of autism in the U.S. — a position in stark contrast with the view of the medical establishment.”
I have criticized Jake Tapper, who wrote the ABC new piece, but he did the right thing here by linking to a lot of evidence that McCain is just plain wrong. That last link is particularly interesting: a study has shown that diagnoses of autism continued to rise even after thimerosal was removed from most vaccines, which makes it pretty unlikely that thimerosal is responsible for that increase.
This matters. Measles can have serious complications:
“Measles itself is unpleasant, but the complications are dangerous. Six to 20 percent of the people who get the disease will get an ear infection, diarrhea, or even pneumonia. One out of 1000 people with measles will develop inflammation of the brain, and about one out of 1000 will die.”
As I write, there’s an outbreak of measles in San Diego. None of the children who got measles had been immunized. Those kids did not decide for themselves to buy into a discredited theory about the dangers of vaccines: their parents did. Moreover, while infants are generally protected against measles by maternal antibodies for their first 6-8 months, they are not vaccinated against measles until they are 12-15 months old. This means that there are a few months when they are susceptible to measles. This window would be a lot less dangerous if every child was vaccinated, since these kids would never encounter children who got measles because their parents were idiots.
Mark Kleiman points out that McCain has also advocated discontinuing methadone after 6 months, which also flies in the face of available research. And, moving from science to other issues, the WSJ notes that McCain has apparently disowned his own Social Security policy:
