On Sept. 3, 2025, California Governor Gavin Newsom, Oregon Governor Tina Kotek, and Washington Governor Bob Ferguson announced they will launch a new West Coast Health Alliance to ensure residents remain protected by science, not politics. The alliance represents a unified regional response to the Trump Administration’s destruction of the U.S. CDC’s credibility and scientific integrity.

“The dismantling of public health and dismissal of experienced and respected health leaders and advisors, along with the lack of using science, data, and evidence to improve our nation’s health are placing lives at risk,” said Erica Pan, MD, MPH, FIDSA, FAAP, Director and State Public Health Officer, California Department of Public Health. “California stands together with our public health and medical professional colleagues to uphold integrity and support our mission to protect the health of our communities.”

Our three states share a commitment to ensuring 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 California, Oregon, and Washington are informed by trusted scientists, clinicians, and other public health leaders. Through this partnership, the three states will start coordinating health guidelines by aligning immunization recommendations informed by respected national medical organizations. This will allow residents to receive consistent, science-based recommendations they can rely on — regardless of shifting federal actions.

Since its founding, the CDC has been central to protecting Americans from disease. But recent leadership changes, reduced transparency, and the sidelining of long-trusted advisory bodies have impaired the agency’s capacity to prepare the nation for respiratory virus season and other public health challenges. In a vacuum of clear, evidence-based vaccine guidance, manufacturers lack reliable information to plan production, health care providers struggle to provide consistent plans of care, and families face uncertainty about access and coverage.

In June, California, Oregon, and Washington condemned Secretary Robert F. Kennedy Jr.’s removal of all 17 members of the CDC’s Advisory Committee on Immunization Practices. Today, we reaffirm our commitment to science-driven decision-making. We will continue to provide clear, evidence-based guidance to people living in our states, look to scientific experts in trusted medical professional organizations for recommendations, and work with public health leaders across the country to ensure all Americans are protected. The absence of consistent, science-based federal leadership poses a direct threat to our nation’s health security. To protect the health of our communities, the West Coast Health Alliance will continue to ensure that our public health strategies are based on best available science.
