California co-leads multi-state lawsuit against CDC’s vaccine recommendations 

By Lake County News Reports | Feb. 25, 2026

Gov. Gavin Newsom on Tuesday announced that California is co-leading a multi-state lawsuit against Robert F. Kennedy Jr., the U.S. Department of Health and Human Services, the CDC, and the CDC’s director for what Newsom’s office called their “unprecedented attack on the country’s evidence-based childhood vaccine schedule.”

The lawsuit includes 15 states suing the federal government for Health and Human Services and CDC’s decision in January to strip seven childhood vaccines of universally recommended status. 

This decision was made circumventing federal laws and without solid scientific supporting evidence, and will certainly result in more kids contracting preventable diseases.

"California is going back to court because the Trump administration is violating federal law and pushing a reckless, unscientific childhood vaccine schedule that puts kids’ lives at risk,” said Newsom. “These changes ignore decades of medical evidence and will lead to outbreaks of diseases we’ve already beaten. We will not stand by while politics overrides science and endangers our children. Just as we’ve done before, we’re standing up — alongside 14 other states — to defend the law, protect public health, and keep our kids safe.”
 
"The Trump Administration’s attacks on science are irresponsible and dangerous,” said Attorney General Rob Bonta. “Undermining confidence in vaccines will lead to lower vaccination rates and more infectious disease. It will also drive up costs for states, including increased Medicaid spending and new expenses to combat misinformation and revise public health guidance. Public health decisions must remain grounded in truth and facts. That’s why, for the 59th time, I’m taking the Trump Administration to court. My fellow attorneys general and I cannot sit on the sidelines while lives are put at risk and our laws are broken.”

State officials said the federal government’s move to advance a childhood vaccine schedule unsupported by science, without deliberation or public input, and circumventing established processes and procedures, is unlawful.

It stands in direct violation of federal requirements that mandate the CDC’s Advisory Committee on Immunization Practices, or ACIP, which advances vaccine recommendations for the country, be fairly balanced.  

Robert F. Kennedy Jr. cleared ACIP of all 17 voting members last summer – something he swore under oath during his confirmation hearing in Congress not to do – replacing the committee with anti-vaccine activists. 

The federal requirements guiding ACIP are meant to ensure that vaccine policy emerges from a body of independent and multi-disciplinary experts guided by evidence-based decision-making. 

“The Trump administration’s bucking of an evidence-based childhood vaccine schedule is especially dire as the United States experiences the highest numbers of measles cases, outbreaks, hospitalizations, and deaths in more than 30 years, driven by populations with low vaccination rates,” the statement from the Governor’s Office said.
