A few weeks ago we conducted a survey of Our Take readers that included both listeners to our podcast and those who don’t (the latter group, we assume, was interested enough to complete a survey). We asked for questions you would like John to answer, and we got some great ones, including today’s question about vaccines and the long-debunked link between the MMR vaccine and autism spectrum disorder. In this first mailbag episode, John reviews the evidence, calls out the "revised" CDC website, and provides his thoughts on the cost of misinformation and disinformation — and what to do about it.
