WASHINGTON (AP) — U.S. regulators approved updated COVID-19 shots Wednesday but limited their use for many Americans — and removed one of the two vaccines available for young children.
The new shots from Pfizer, and are approved for all seniors. But the narrowed their use for younger adults and to those with at least one high-risk health condition, such as asthma or obesity. That presents for millions of Americans who would have to prove their risk — and millions more who may want to get vaccinated and suddenly no longer qualify.
Additionally, Pfizer’s vaccine will no longer be available for any child under 5, because the FDA said it was revoking the shot’s emergency authorization for that age group.
Parents will still be able to seek out shots from rival drugmaker Moderna, the other maker of mRNA vaccines, which has full FDA approval for children as young as 6 months. But the company’s vaccine is only approved for children with at least one serious health problem.
The target a newer version of the continuously evolving virus and are set to begin shipping soon. But it could be days or weeks before many Americans know if they’ll be able to get one, with access dependent on decisions by federal health advisers, health insurers, pharmacies and state authorities.
The new restrictions — previewed by FDA officials in May — are a break from the previous U.S. policy, which recommended an annual COVID-19 shot for all Americans 6 months and up.
The approach reflects about the ongoing risks of COVID-19 and the need for yearly booster shots from and , both of wide-scale vaccinations.
“The American people demanded science, safety, and common sense. This framework delivers all three,†Kennedy wrote on social media.
Novavax's shot is only open to people 12 or older, not younger children, and carries the same risk-based restrictions that are now in place for Moderna and Pfizer. It's the nation's only traditional, protein-based COVID-19 vaccine.
Coverage questions and access issues are unresolved
The new limits "can’t help but create barriers to vaccinations†and cause confusion for patients, doctors and pharmacists, said Dr. William Schaffner, a Vanderbilt University vaccines expert.
Some medical groups, including the American Academy of Pediatrics, have objected to the restrictions, saying they may block vaccine access for families who want to protect their children. Last week, the group offered for kids, saying annual shots are strongly recommended for children ages 6 months to 2 years and advised for older children.
In his post Wednesday, Kennedy said the shots will be "available for all patients who choose them after consulting with their doctors.â€
But Americans are likely to confront a number of .
Insurers typically base their vaccine coverage decisions on the recommendations of a panel of advisers to Centers for Disease Control and Prevention, but some say they will also look to medical professional groups, including the American Medical Association.
Earlier this year, Kennedy replaced the entire , naming several doctors and researchers who have repeatedly questioned the safety of commonly used vaccines and ingredients. The panel is expected to meet in September, but no agenda has been released.
Depending on the panel’s advice, Americans under age 65 could be expected to provide documentation of a serious medical problem before they can get a shot. Also complicating the rollout is the fact that pharmacists — who administer most COVID-19 shots — typically aren’t expected to collect that kind of information. And laws governing their ability to administer routine vaccinations vary by state.
Access could also be complicated for healthy adults and children who are interested in getting a shot for extra protection.
If the latest vaccines aren’t covered by their insurance, those patients could be required to pay $150 or more out of pocket if they want one. If they aren't considered high-risk, they might also have to find a doctor or other health professional willing to give the shot “off label." Many pharmacists might be reluctant to give the shots outside of FDA's instructions.
“This makes things much more complicated, and when things get complicated we see vaccine uptake go down,†said Andy Pekosz, a virologist at Johns Hopkins University.
Shots target a recently dominant coronavirus version
The updated shots target coronavirus subtypes that are closely related to some newly emerging cousins. Pfizer and Moderna said they expect their shots to be available within days. Novavax's vaccine is expected in the early fall, a spokesman said.
Shots from all three companies were initially made available under the FDA’s emergency use authorization, an expedited process to quickly review vaccines, drugs and other countermeasures during the pandemic. Pfizer had not yet sought full approval for its doses designed for children under 5, which is the reason that Moderna will be the only provider of shots for that age group this year.
In addition to revoking emergency use of Pfizer’s vaccine in young children, Kennedy said Wednesday the government also pulled remaining authorizations for all other COVID-19 vaccines and another therapy from the pandemic years, convalescent plasma, which was used to treat hospitalized patients before the first antiviral drugs became available.
COVID-19 vaccines do a good job preventing severe disease, hospitalization and death, which remain a bigger risk for seniors, young children and people with underlying health risks.
Preliminary data from the CDC estimates 47,500 Americans died from COVID-related causes last year.
Some experts worried that fewer vaccinations could increase the strain on hospitals over the winter, when cases tend to accelerated.
“Down the line, this will really stress our health workforce,†said Amanda Jezek, of the Infectious Diseases Society of America. “The public health impacts here are very worrisome.â€
