States are taking action to protect vaccine access amid changes in federal policy under HHS Secretary Robert F. Kennedy Jr. Kennedy's actions, including replacing the Advisory Committee on Immunization Practices (ACIP) and banning thimerosal (a preservative), have raised concerns. States like Colorado and Maine are enacting legislation to ensure continued access to vaccines, even if ACIP recommendations change, referencing other medical organizations and protecting insurance coverage. This proactive approach aims to maintain access to lifesaving vaccines despite potential shifts in federal guidelines.
