Six medical groups alongside a pregnant physician have filed a lawsuit against Health and Human Services Secretary Robert F. Kennedy Jr. challenging his changes to federal COVID-19 vaccine recommendations. The directive removed vaccines from routine recommendations for pregnant individuals and healthy children, replacing it with a shared clinical decision-making guideline. Plaintiffs including the American Academy of Pediatrics and Infectious Diseases Society of America argue this action undermines established vaccine infrastructure and creates public health risks. Legal concerns also highlight insurance coverage ambiguities sparked by the shift away from blanket vaccine endorsements.
