A coalition of 15 governors launched the Governors Public Health Alliance in mid-October 2025, saying it will help states and a U.S. territory coordinate on public health guidance, data-sharing and emergency preparedness as federal health policy shifts and regional state alliances expand.
In mid-October 2025, a group of 15 governors launched the Governors Public Health Alliance, a coalition intended to strengthen cross-border coordination on public health guidance, emergency preparedness and information-sharing. California Gov. Gavin Newsom announced the initiative on Oct. 15, describing it as a nonpartisan effort to keep public health decisions “driven by data” rather than politics.
According to announcements from participating states, the alliance includes the governors of California, Washington, Oregon, Hawaii, Colorado, Connecticut, Delaware, Illinois, Maryland, Massachusetts, New Jersey, New York, North Carolina and Rhode Island, as well as the governor of Guam. The effort is supported by GovAct, a nonprofit organization that has helped governors form multi-state coalitions on other policy areas.
The new alliance builds on regional collaborations that emerged in 2025. On the West Coast, California, Oregon, Washington and Hawaii formed the West Coast Health Alliance to align vaccine and respiratory-virus guidance and to issue recommendations informed by major medical organizations. In the Northeast, several states and New York City formally announced the Northeast Public Health Collaborative in September 2025 as a voluntary coalition to share expertise and coordinate on preparedness, vaccine recommendations, data collection and infectious-disease management.
Public health authority in the United States is divided among federal, state and local governments. States and localities handle much of the day-to-day work of immunizations and outbreak response, while the federal government plays a major role in national disease surveillance, research funding and issuing guidance that state and local agencies often use.
The creation of the governors’ alliance comes amid intensified debate over vaccines and other public health measures. In Florida, state Surgeon General Joseph Ladapo said in early September 2025 that the state aimed to eliminate school vaccine mandates, but subsequent reporting and state health department statements indicated the immediate rulemaking effort targeted only some vaccines and would not end mandates for diseases such as measles and polio without legislative action.
In Idaho, lawmakers approved a “Medical Freedom Act” in 2025 that critics and legal analysts say sharply limits the ability of government—and, in some cases, private entities—to require certain medical interventions, including vaccination, unless mandated by federal law. Supporters have framed the law as protecting individual choice.
The broader public health landscape has also been shaped by large disease outbreaks that cross state lines. A major measles outbreak that began in West Texas in early 2025 spread into neighboring states including New Mexico and later reached Kansas and Oklahoma, underscoring how quickly infectious diseases can move across jurisdictions.
Separately, an analysis by KFF Health News found that after the U.S. Department of Health and Human Services canceled hundreds of CDC grants in 2025 and a court later blocked the cancellations for jurisdictions that sued, the bulk of restored grants were in Democratic-led states that participated in the lawsuit, while many Republican-led states that did not sue saw far fewer grants reinstated.
Governors behind the new alliance say the goal is to improve coordination—such as sharing data, aligning emergency plans and supporting access to vaccines—while leaving policy decisions to states. The coalition’s organizers have also argued that multi-state collaboration can help reduce confusion for residents who live, work and travel across state lines.
