Yesterday, results of a survey on beliefs about vaccines circulated on the internet. The survey conducted last week, asked over 2000 adults if they believed vaccines, or the MMR shot, caused autism. I’m not an expert on surveys and I don’t know how reproducible these results are to all parents in the US. But the news caught my eye (along with many others) when they reported: “Just a slim majority of Americans — 52 percent — think vaccines don’t cause autism” That’s a kind-of-odd-double-negative-type way to look at it, I suppose. Or maybe a hopeful one. The results reflect that nearly half of adults in America may suspect or worry that vaccines cause autism; 18% saying they believe a connection exists.
The survey reminds us of some of the Why. It seems on some level, it’s a breakdown in our education. While only “69 percent of respondents said they had heard about the autism-vaccination theory — only half (47 percent) knew that the original Lancet study [that linked vaccines and autism] had been retracted, and that some of that research is now alleged to be fraudulent.” And, the details of all the research finding no link between autism and MMR is even more deeply buried, I suspect.
Even so, the numbers surprised me. In light of all the writing in the British Medical Journal this month on the scam behind Andrew Wakefield’s original paper in 1998 making the claim, I’ve been thinking about where we all stand in our understanding of immunizations, science, and trust. More on that next week. But I really wouldn’t have said 1/2 of my patient’s parents believed or suspected in a connection between autism and vaccines. What percentage would you have guessed?
