Study: You Can't Change an Anti-Vaxxer's Mind [View all]

Vaccine denial is dangerous. We know this for many reasons, but just consider one of them: In California in 2010, 10 children died in a whooping cough outbreak that was later linked, in part, to the presence of 39 separate clusters of unvaccinated children in the state. It's that simple: When too many children go unvaccinated, vaccine-preventable diseases spread more easily, and sometimes children die. Nonetheless, as scientifically unfounded fears about childhood vaccines causing autism have proliferated over the past decade or more, a minority of parents are turning to "personal belief exemptions," so-called "alternative vaccine schedules," and other ways to dodge or delay vaccinating their kids.

So as a rational person, you might think it would be of the utmost importance to try to talk some sense into these people. But there's a problem: According to a major new study in the journal Pediatrics, trying to do so may actually make the problem worse. The paper tested the effectiveness of four separate pro-vaccine messages, three of which were based very closely on how the Centers for Disease Control and Prevention (CDC) itself talks about vaccines. The results can only be called grim: Not a single one of the messages was successful when it came to increasing parents' professed intent to vaccinate their children. And in several cases the messages actually backfired, either increasing the ill-founded belief that vaccines cause autism or even, in one case, apparently reducing parents' intent to vaccinate.
