SACRAMENTO —
Governor Gavin Newsom has enacted a law that empowers California to establish its own immunization schedules, shifting away from decades of federal guidance and aligning more with state health experts and independent medical groups.
This change coincided with recommendations issued by California and its West Coast allies regarding COVID-19, flu, and RSV vaccines. These states formed a coalition aimed at countering what they perceive as a politicized approach from the U.S. Centers for Disease Control and Prevention (CDC).
The governors of California, Oregon, Washington, and Hawaii stated, “Our states are united in putting science, safety, and transparency first — and in protecting families with clear, credible vaccine guidance.”
This healthcare debate arises in the wake of increasing COVID cases and the upcoming flu season. Traditionally, the CDC has served as the nation’s leading authority on vaccines, setting standards for childhood immunizations, guiding adult vaccination practices, and influencing public health policies nationwide.
However, under the direction of Health and Human Services Secretary Robert F. Kennedy Jr., who is a Trump associate, the CDC has undergone significant leadership changes, resulting in the departure of senior scientific advisors and a reconstitution of its advisory committee with members promoting misinformation about vaccines. This committee is scheduled to convene soon to discuss potential updates to vaccine recommendations.
Kennedy defends the restructuring as a step towards restoring trust and removing politics from scientific discussions, asserting that the public deserves accurate information.
Meanwhile, former CDC chief Susan Monarez warned senators that the U.S. public health system is heading into precarious territory under Kennedy’s guidance, claiming she faced pressure to approve vaccine recommendations lacking scientific support.
The turmoil at the CDC has led to strong backlash, with more than a thousand current and former health employees demanding Kennedy’s resignation. Yet, some states are adopting a different stance; for instance, Florida plans to eliminate all mandatory vaccinations, even for children in schools.
This division is impacting public perception. A recent KFF poll indicates that many Americans are increasingly uncertain about health guidelines and their implications for safety.
Experts emphasize that vaccines are vital for both individual and community health, ultimately reducing healthcare costs by preventing disease outbreaks.
Recent changes by federal health agencies have been extensive. For example, under Kennedy’s oversight, the FDA now advises adults 65 and younger without health issues to consult a healthcare provider prior to receiving the COVID vaccine. Similarly, the CDC has mandated that parents speak with a healthcare provider before their healthy children can receive the vaccine—something the American Academy of Pediatrics has termed “deeply troubling.”
The American Academy of Pediatrics has released its own guidance recommending that all children aged 6 to 23 months receive the COVID vaccine, as well as certain older children who are at higher risk.
In a notable shift, the CDC has changed its recommendation for pregnant women, offering no guidance on whether healthy expectant mothers should be vaccinated. In contrast, the American College of Obstetricians and Gynecologists now advises that individuals should consider receiving the updated COVID-19 vaccine at any point during pregnancy.
Following this trend, California has decided to disregard CDC guidance, starting with the new recommendations from the West Coast Health Alliance. These recommendations are based on input from health officials and expert groups from each state, considering perspectives from organizations like the American Academy of Pediatrics.
Specifically, the alliance’s COVID-19 vaccine recommendations advocate for immunization for all children aged 6 to 23 months, seniors aged 65 and older, and individuals between 2 and 64 who have risk factors. They also recommend vaccination for all pregnant and postpartum women.
It’s further suggested that individuals in close contact with others at risk for severe COVID-19 illness should be vaccinated, as well as children who have never been vaccinated against COVID-19.
The guidance for adults varies slightly, as recommended by the American Academy of Family Physicians, which advocates that all adults receive the updated COVID vaccine.
As for flu and RSV vaccines, the alliance suggests that everyone aged 6 months and older should receive the flu shot and that the RSV vaccine should be administered to children under 8 months and older adults with risk factors, as well as pregnant women between 32 and 36 weeks gestation.
Dr. Jake Scott from Stanford School of Medicine expressed that the West Coast Health Alliance’s recommendations send a strong message that state governments will prioritize science over federal inconsistency.
With Newsom’s approval of Assembly Bill 144, California has revised its law previously based on CDC recommendations, which will now focus on advice from a broader range of medical associations by January 1, 2025.
This law also enables the California Department of Public Health to adjust immunization recommendations based on input from various medical and scientific organizations. It extends liability protections for vaccine-related injuries that might occur due to deviations in recommendations, not covering gross negligence or deliberate misconduct, until the year 2030.
Dr. Erica Pan, director of the California Department of Public Health, emphasized the commitment of public health and scientific communities to provide clear, evidence-based guidance for making healthy choices.
In conjunction with these developments, California lawmakers and the University of California are pushing for a $23 billion ballot measure aimed at compensating for federal research funds lost to cuts during the Trump administration, highlighting efforts to protect scientific integrity and public health.
Theresa Maldonado, the UC’s vice president for research, highlighted the severe implications of lost federal funding, noting it creates a critical situation for the state and its communities.
