The final nail in the coffin for the antivaccine rallying cry “Too many too soon”?

There are some weeks when I know what my topic will be—what it must be. These are weeks in which the universe gives the very appearance of handing to me my topic for the week on the proverbial silver platter with a giant hand descending from the clouds, pointing at it, and saying, “Blog about this, you idiot!” Usually, it’s because a study is released or something happens or a quack writes something that cries out for rebuttal. Whatever it is, it’s big and it’s unavoidable (for me, at least).

This is one of those weeks.

The reason it’s one of those weeks is because just last Friday, as I was driving to work, I heard a news story on NPR about a study that had just been released in the Journal of Pediatrics. The story, as it was reported, noted that the study being discussed looked specifically at a certain antivaccine trope and found for yet the umpteenth time that vaccines are not correlated with an increased risk of autism. Normally the news that a study had once again failed to find a link between vaccines and autism would be as surprising as a study finding that the sun rises in the east and sets in the west, or finding that water boils at 100° C at sea level. At this point, the evidence is so utterly overwhelming that there is not a whiff of a hint of a whisper of a correlation between vaccines and autism that it has become irritating that antivaccine activists keep pressuring scientists to do the same study over and over again, coming up with the same results over and over again, and then seeing antivaccinationists fail to believe those same results over and over again. Apparently, antivaccine activists think that if the same sorts of studies are done enough times, there will be a positive result implicating vaccines as a risk factor for or contributing cause to autism. By sheer random chance alone, this might happen someday, given the definition of statistical significance, but so far there has not been a single large, well-designed epidemiological study by reputable researchers that has found a link.
