evidence: THE FACTS: The Centers for Disease Control and Prevention last week recommended babies receive a new shot to help protect them from RSV, a virus that is a cold-like nuisance for most healthy people but that can be dangerous for the very young and elderly. The move followed the Food and Drug Administration’s approval of the drug, a lab-made antibody called nirsevimab developed by AstraZeneca and Sanofi that will be sold under the brand name Beyfortus. [...] "Despite 12 Deaths During Clinical Trials, CDC Signs Off on RSV Shots for Newborns," reads the headline in the posts. The headline comes from the website of Children’s Health Defense, an anti-vaccine group founded by now-presidential candidate Robert F. Kennedy Jr. [...] An FDA briefing document reports that 11 babies who received the shots died; another who died had received an existing RSV drug called palivizumab. Some died from acute gastroenteritis and pneumonia; one suffered a skull base fracture in a car accident. Some of the babies also had underlying comorbidities, such as congenital heart disease or being born prematurely.
