There’s nothing wrong with being a little crunchy, but we’re well beyond the recommended dosage here. America’s top health official, Robert F. Kennedy Jr., staked his political career on the false belief that vaccines cause autism, and has used his power to force federal agencies to support his bonkers position: The CDC’s website now says, “Studies have not ruled out the possibility that infant vaccines cause autism.” Thanks to Kennedy and others, measles outbreaks are happening all over the country after the disease was declared officially eliminated in the U.S. 26 years ago. More than 3,200 cases (since the start of 2025) and at least two deaths of unvaccinated children later, the head of Medicare and Medicaid, Mehmet Oz—you might remember him for his clout-chasing attempt to foment panic about arsenic in apple juice—was driven to beg Americans to trust the measles-mumps-rubella vaccine.
