As much time and effort as I spend deconstructing, refuting, and otherwise demolishing the misinformation that is routinely promulgated about vaccines by the antivaccine movement, it's important never just to reflexly dismiss a claim or news story that gains traction among antivaccinationists. After all, it is always possible that the story is as the antivaccinationists represent it; possible, but not likely. Still, one must be careful not to be so close-minded that one leaps to dismiss a story just because of its source.
