Since becoming U.S. Secretary of the Department of Health and Human Services (HHS), Robert F. Kennedy Jr. has taken dangerous steps to sow vaccine mistrust and also to take away people’s access to life-saving vaccines. His actions are confusing parents, breaking trust, and creating a vaccine policy mess across states, which is putting public health at risk. Sign now to protect your family and others. Tell Trump and your U.S. Senators: Fire RFK Jr. before more harm is done.
