One of the more bizarre things that have happened related to the COVID-19 pandemic is the way that antivaccine activists have formed an unholy alliance with COVID-19 conspiracy theorists. On the other hand, it might seem bizarre to those not familiar with antivaccine pseudoscience, but it actually makes perfect sense to those of us who have been following the antivaccine movement for a long time, for the simple reason that all antivaccine pseudoscience is based on conspiracy theories. So it isn’t much of a surprise that someone I’ve been following for a very long time (16 years!) has gone all-in on COVID-19 conspiracy theories. I’m referring to J.B. Handley, the man who, with his wife, founded Generation Rescue, an antivaccine group dedicated to the now refuted hypothesis that mercury in vaccines causes autism. When last we met him three years ago, he was once again attacking vaccine science and spewing his usual antivaccine misinformation. Before that, he was known for misogynistic attacks on female journalists writing about antivaxxers and attacks against defenders of science in general. These days, he’s posting his pseudoscience on the website of Robert F. Kennedy, Jr.’s antivaccine group Children’s Health Defense in an article entitled “LOCKDOWN LUNACY: The Thinking Person’s Guide.” It’s useful to examine, because it’s basically a cornucopia of COVID-19 misinformation, disinformation, and conspiracy theories.
