Revised CDC Website About Autism and Vaccines Is Not Evidence-Based

Under Robert F. Kennedy Jr., a longtime anti-vaccine advocate who is now Health and Human Services secretary, the Centers for Disease Control and Prevention revised its website to say that its previous statement that “vaccines do not cause autism” is “not an evidence-based claim.” But it’s the revised website that misleads about vaccines.
