This is about antivaccine happenings ten years’ time ago. Unfortunately, it’s also about antivaccine happenings now. The reason, and what links the two, is that antivaccine happenings, particularly myths, never seem to die. They just keep coming back over and over again. One myth that’s been recycled since at least 2005 is the one that claims that there’s been a study that has vindicated Andrew Wakefield. Stories pop up every so often that look for all the world as though they’re new claiming that the results of Andrew Wakefield’s original Lancet case series has been replicated. Sadly for Wakefield (and happily for the rest of the world), it’s just not true. I have a Google Alert for vaccines set up, so I see these stories when they pop up periodically. Sometimes they even make an appearance on Facebook and/or Twitter as antivaccine memes.
This time around, what’s happening is not exactly the same thing. The “Wakefield was right” news stories appear to arise organically every so often. I have no idea why. This particular story is one that’s being desperately pushed by antivaccine mavens—again. It’s one that has been desperately promoted dating back to a decade ago, as you will see. Unfortunately, like Jason or Michael Myers in a classic slasher flick, just when you think it’s dead is the time to be vigilant because it’s not. I’m referring to a myth that I’ve been covering on and off for nearly a decade that the Centers for Disease Control (the CDC) has been “hiding evidence” that mercury in vaccines is a major cause of the “autism epidemic.” It’s not true, of course. Indeed, my very first post for this blog lo these six years ago referred to the hypothesis that mercury in the thimerosal preservative that used to be used in childhood vaccines as a failed hypothesis. And so it is—and remains.
