A pediatrician, author and co-inventor of a low-cost COVID-19 vaccine warns that the anti-vaccine movement has morphed into a political force that threatens the world’s gains against deadly childhood infections like measles.

Dr. Peter Hotez, author of the new book The Deadly Rise of Anti-Science: A Scientist’s Warning, says the movement is well organized, well financed and includes powerful organizations in the U.S. such as the Republicans’ House Freedom Caucus, certain senators and what he calls “contrarian-” and “pseudo-intellectuals.”

Some are now looking to target routine childhood and adult immunizations, he told White Coat, Black Art host Dr. Brian Goldman.
