In response to changes made by Health Secretary Robert F. Kennedy Jr. to the federal Advisory Committee on Immunization Practices, the Washington state legislature has passed a bill requiring insurers to follow the state's own vaccine recommendations rather than the federal guidelines. This comes after Washington and other Western states issued their own vaccine recommendations last fall, rejecting the federal policy changes.

Why it matters

The legislation aims to maintain public trust in vaccine guidance by relying on recommendations from the state's Department of Health, which will be guided by scientific consensus, rather than the federal panel that has been overhauled with vaccine skeptics. This is part of a broader effort by Western states to chart an independent course on vaccine policy amid concerns about the federal government's changes.

The details

The Washington bill, House Bill 2242, requires insurance companies to cover the state-recommended immunizations for health plans starting or renewing after April 1. This overrides the federal Advisory Committee on Immunization Practices, which Kennedy has filled with anti-vaccine activists, replacing the previous panel of vaccine experts. The state is joining Oregon, California and Hawaii in the West Coast Health Alliance to issue its own vaccine guidance independent of the federal government.

  • In January, Washington Governor Bob Ferguson called for the state to 'shift vaccine recommendations away from science-denying federal committees'.
  • The Washington state legislature passed the bill on Thursday, February 27, 2026.
  • The bill will take effect immediately after being signed by the governor in the coming days.
