West Coast Health Alliance

In September 2025, the governors of Oregon, California, Hawaii, and Washington formed the West Coast Health Alliance. The alliance represents a unified regional response to ensure that public health recommendations are guided by safety, efficacy, transparency, access, and trust. The Alliance will help safeguard scientific expertise by ensuring that public health policies in Oregon, California, Hawaii, and Washington are informed by trusted scientists, clinicians, and other public health leaders. Through this partnership, the four states will coordinate health guidelines by aligning immunization recommendations informed by respected national medical organizations. This will allow residents to receive consistent, science-based recommendations on which they can rely.
