Recently, there was another nail in the coffin for vaccine skeptics. The British medical journal The Lancet took the dramatic step of retracting a 1998 paper that lies at the root of modern vaccine denialism. Authored by a doctor named Andrew Wakefield and his colleagues, it was heavily touted as having uncovered a new cause of autism—the measles, mumps, rubella vaccine, or, the MMR vaccine.

Not so fast. Twelve years later, there are more problems with the paper than you can count—and yet somehow, it managed to spawn a movement.

In this conversation with host Chris Mooney, Dr. Paul Offit— author of  Autism’s False Prophets: Bad Science, Risky Medicine, and the Search for a Cure—discusses the state of the vaccine skeptic movement in light of this latest news. In particular, Offit explores why the tides may be turning on the movement—as well as the grave public health consequences of ongoing vaccine avoidance.

Paul A. Offit, MD is the Chief of the Division of Infectious Diseases and the Director of the Vaccine Education Center at the Children’s Hospital of Philadelphia. In addition, Dr. Offit is the Maurice R. Hilleman Professor of Vaccinology and a Professor of Pediatrics at the University of Pennsylvania School of Medicine. Dr. Offit has published more than 130 papers in medical and scientific journals in the areas of rotavirus-specific immune responses and vaccine safety. He is also the co-inventor of the rotavirus vaccine, RotaTeq, recommended for universal use in infants by the CDC. Dr Offit was a member of the Advisory Committee on Immunization Practices to the Centers for Disease Control and Prevention, is a founding advisory board member of the Autism Science Foundation, and is the author of five books, the latest of which is Autism’s False Prophets.
