As Subvariant Spreads, CDC Maintains Child Vaccine Guidance Despite RFK Announcement

Amid reports of a new Covid-19 subvariant spreading in several U.S. states, the Centers for Disease Control and Prevention on Friday said updated guidance on receiving vaccines against the coronavirus that contradicted a controversial recent announcement from the nation's top health official.

The CDC's schedule for vaccines for children aged 6 months to 17 years retained the Covid-19 shot, advising parents and doctors to engage in "shared clinical decision-making" when determining if a child should be vaccinated—meaning children can receive the shots if their parents and physicians agree.

That guidance contradicts a statement from Health and Human Services Secretary Robert F. Kennedy, Jr. earlier this week. Kennedy claimed Tuesday that there was a "lack of any clinical data to support the repeat booster strategy in children" for Covid vaccines as he announced, alongside National Institutes of Health Director Dr. Jay Bhattacharya and Food and Drug Administration (FDA) Commissioner Dr. Martin Makary, that the shots would no longer be recommended for pregnant women or healthy children.

"Where the parent presents with a desire for their child to be vaccinated, children six months and older may receive Covid-19 vaccination, informed by the clinical judgment of a healthcare provider and personal preference and circumstances," the new guidelines read.

"At least how some clinicians perceive it is, 'You guys are the experts, and if you don't know what the right thing to do is, how are we supposed to have that conversation in a 10-minute office visit?'"

Kennedy's announcement earlier this week alarmed public health experts, as did an earlier statement that the vaccines would only be made available to people over age 65 and those with certain medical conditions.

Kennedy, who baselessly called the Covid-19 vaccine "the deadliest ever made" in 2021—when the shots were estimated to have saved 140,000 lives—said at the time that new clinical trials would be needed to see if the vaccines continued to provide protection to people under 65.

Sean O'Leary, the chair of the American Academy of Pediatrics' infectious disease committee, said the CDC's new guidance could still cause confusion among parents and doctors, compared to an across-the-board recommendation like those that exist for other childhood vaccines.

"At least how some clinicians perceive it is, 'You guys are the experts, and if you don't know what the right thing to do is, how are we supposed to have that conversation in a 10-minute office visit?'" O'Leary told The Washington Post.

But the new guidance could stop insurance companies from refusing to cover the shots, as experts were worried they might after Kennedy's earlier statements, and will preserve the shots' availability for about 38 million low-income children who rely on the Vaccines for Children program.

The out-of-pocket cost for a Covid vaccine at a CVS pharmacy—where some patients could opt to go if their doctors don't want to administer the vaccine—is $198.99.

Experts remained concerned on Friday about the CDC's approach to Covid vaccines for pregnant women; the agency said there is officially "no guidance" for people who are pregnant.

Public health experts have warned that research shows pregnant women's risk of death and hospitalization is heightened if they have a Covid infection, and that the illness raises the risk of stillbirth.

The CDC's new guidance—and Kennedy's push to pivot away from Covid vaccines for the general population—come as a new, highly transmissible Covid subvariant has been detected in states including California, Rhode Island, New York, and Washington.

The subvariant, NB.1.8.1, was first detected in January and has been spreading in Europe and Asia since then, with the World Health Organization saying there has been a "concurrent increase in cases and hospitalizations in some countries where NB.1.8.1 is widespread."

Dr. Yvonne Maldonado, an infectious disease expert at Stanford University, told The Los Angeles Times that NB.1.8.1 does not cause more severe illness, "but it is more transmissible, at least from what we’re seeing around the world and also from lab experiments."

Meanwhile, Kennedy's push to reduce the availability of vaccines is "kind of chilling," Dr. Peter Chin-Hong of the University of California, San Francisco, told the Times. "It's out of step with the system we've learned to trust and follow... Most people would agree that kids should be targeted for flu vaccines. It seems kind of weird to have Covid as an outlier in that respect."

O'Leary said in a statement that despite the Trump administration's recent statements, scientific data about the vaccines is clear.

"Pregnant women, infants, and young children are at higher risk of hospitalization from Covid," he said, "and the safety of the Covid vaccine has been widely demonstrated."
