Robert F. Kennedy Jr.’s Department of Health and Human Services (HHS) may drop the federal guidance that recommends vaccination against Covid for children, teenagers, and pregnant women.

HHS may remove Centers for Disease Control and Prevention’s (CDC) recommendations as it weighs new guidance for vaccine approval, according to a Wall Street Journal report released on Thursday. The CDC recommends vaccination against Covid for everyone six months and older, including pregnant women.

The revision to CDC recommendations is expected to be announced in the coming days.

Kennedy, a famous vaccine skeptic, has been vocal about his opposition to the Covid vaccine requirement campaign and mRNA vaccines. Along with newly appointed officials in President Donald Trump’s Food and Drug Administration (FDA), Kennedy has questioned the efficacy of the Covid shot for younger, low-risk individuals.

“Separate from my role as a regulator at the FDA, I am not encouraging or insisting young, healthy children to get a Covid shot unless there is new evidence that emerges that suggests there is a clear benefit,” FDA Commissioner Dr. Marty Makary said Thursday during a Food and Drug Law Institute conference.

“We want to see vaccines that are available for high-risk individuals, and at the same time, we want some good science. We want some good clinical data,” Makary added.

Trump began Operation Warp Speed, the public-health campaign that launched the Covid vaccine effort, during his first term at the onset of Covid. Although the administration took a blanket approach to vaccines and recommended them for most individuals, fewer Americans are now receiving the vaccine. According to CDC data, as of April, 13 percent of children and 14 percent of pregnant women had received the latest Covid vaccine.

It is unclear if health insurers will continue to cover the Covid shot under revised guidelines.

The FDA will also release an updated vaccine framework soon, the WSJ reported, which will detail what companies must do to seek vaccine approval.

“We want to be very transparent,” Makary said. “We want to create a framework for vaccine makers that they can use so they have a predictable FDA where they don’t have to worry how is this going to be received.”
