Kennedy Jr. pressured her to approve vaccine recommendations without scientific evidence, leading to her dismissal and multiple resignations. The controversy comes ahead of key Advisory Committee on Immunization Practices (ACIP) votes on hepatitis B, MMRV, and COVID-19 vaccines for children, raising concerns about potential influences on vaccine access and public health.
