A CDC advisory panel vote to recommend against use of seasonal influenza vaccines containing small amounts of thimerosal followed a presentation that misled on the risks of the rarely used preservative. There isn’t evidence that thimerosal in vaccines is harmful, and studies assessing a variety of health problems, including neurological conditions, have supported its safety.
Robert F. Kennedy Jr. makes a variety of incorrect or misleading claims about vaccines, COVID-19 and other health-related topics. But his views on vaccines rose to prominence when he began to advance the thoroughly debunked idea that they cause autism.
A popular Instagram post falsely claims “over 1,100 people died from reactions to the [flu] shot” in 2018, and suggests that the immunization gave some children polio. The flu vaccine cannot give anyone polio and there is no evidence to support the 1,100 figure.
