California Attorney General Rob Bonta said on Feb. 17 that the state plans to take legal action against the Trump administration over the recent modifications to the childhood vaccine schedule.

The Centers for Disease Control and Prevention (CDC) on Jan. 5, with backing from Health Secretary Robert F. Kennedy Jr., narrowed the number of vaccines routinely recommended by the childhood schedule.

Bonta told Reuters in an interview that he has mobilized his team to identify the necessary details for a possible complaint against the Department of Health and Human Services (HHS), including jurisdictional and legal grounds for pursuing the lawsuit.

“I like the facts. I like science. I don’t want to give any airtime to his—I mean, just conspiracy [expletive],” Bonta told the news agency, referring to Kennedy’s stance on vaccines.

Bonta did not specify when the state might file or whether it would be a multistate filing. Connecticut Attorney General William Tong, who also spoke to Reuters, indicated that his state may join California in the filing.

The Epoch Times reached out to HHS for comment but did not receive a response by publication time.

The CDC in January issued a revised childhood vaccine schedule that ended broad recommendations for vaccines against rotavirus, influenza, meningococcal disease, hepatitis A, and hepatitis B.

The agency said in a Jan. 5 memo that decisions for those vaccinations should instead be made through “shared clinical decision-making,” which involves discussion between parents and health care providers.

The changes were made after President Donald Trump directed the HHS and CDC to review U.S. vaccine schedules and compare them with those of peer countries. The president named three countries—Denmark, Japan, and Germany—that recommend fewer vaccines and fewer vaccine doses.

At the time, the White House said in a fact sheet that if the HHS and CDC determine that those practices from developed countries are better than U.S. recommendations, they are directed to update the U.S. core childhood vaccine schedule to align with such scientific evidence and best practices, while preserving access to existing vaccines for Americans.

“Practices like the hepatitis B vaccination at birth are standard in the United States, but uncommon in most developed countries, where it is typically only recommended for newborns of mothers who test positive for the infection,” the White House stated in December.

The American Academy of Pediatrics and other groups filed a lawsuit on Jan. 19 seeking to challenge the revised childhood vaccine schedule.

They argued that officials failed to adequately review relevant data or provide satisfactory explanations for the changes. A federal judge heard arguments on Feb. 13 and is considering whether to block the schedule update.

In January, HHS responded after executives of top vaccine companies took aim at the Trump administration in the wake of a series of actions on vaccines.

“Vaccine recommendations are based on the best available gold-standard scientific evidence and public health considerations, not corporate interests,” an HHS spokesperson told The Epoch Times in an email on Jan. 28.

“Under this administration, HHS is not beholden to the pharmaceutical industry. Decisions are made through transparent processes with the sole aim of protecting the health of the American people. Protecting public health and restoring trust will continue to drive HHS’ vaccine policy.”
