FDA authorizes coronavirus vaccine for young kids with shots likely next week – The Washington Post

“Many parents, caregivers and clinicians have been waiting for a vaccine for younger children and this action will help protect those down to 6 months of age,” FDA Commissioner Robert M. Califf said in a statement. “As we have seen with older age groups, we expect that the vaccines for younger children will provide protection from the most severe outcomes of COVID-19, such as hospitalization and death.”

The vaccines for young children arrive at a critical moment in the nation’s quest to vanquish the virus, with vaccination levels overall flagging even as covid-19 hospitalizations reach their highest average level in more than three months. And they come a few months before the fall, which, along with the winter, could feature another deadly surge of covid cases.

Many parents with babies and young children see the shots as critical to resuming their pre-pandemic lives, without frequent disruptions to day-care schedules or family celebrations. Several parents said they intend to get their children vaccinated as soon as possible.

Yet indications are that initial uptake of the vaccines will be low. In a recent Kaiser Family Foundation survey, only 18 percent said they plan to get their children vaccinated right away, while 27 percent said they will “definitely not” get their child vaccinated.

It’s not unusual for parents to be hesitant when childhood vaccinations first roll out, as was the case with the polio and pneumococcal vaccines, experts said. But it means pediatricians and family doctors, whom polls show parents trust the most, will have to work diligently in coming months to assuage parental anxieties about having their child vaccinated.

“There’s a lot of information and trust building that needs to happen,” said Tom Inglesby, director of the Johns Hopkins Center for Health Security at the Bloomberg School of Public Health. “It’s going to take time to reach other parents, and they’re going to need to really develop confidence in the vaccine and hear it from their most trusted local health-care providers. … Hopefully, with time, people will have increasing confidence that it’s both effective and safe.”

Vaccines tested against earlier lineages of the coronavirus “won’t hold up that well in protecting against infection by the new subvariants,” said Peter Hotez, a molecular virologist and dean for the National School of Tropical Medicine at Baylor College of Medicine in Houston. “But they will still be very effective in preventing children from going to the hospital or the intensive care unit.”

As information about the two vaccines emerges, physicians are sure to debate which is preferable. But many say it will require additional data accumulated during use of the two brands in the real world to determine which is more effective — and that other factors have to be considered, such as side effects. In many cases, parents won’t have a choice because pediatricians might stock just one of the vaccines — though big, hospital-based practices might offer both.

Some parents might prefer the two-shot regimen by Moderna, which can be completed more quickly than the Pfizer-BioNTech three-dose regimen. The Pfizer-BioNTech shot produces fewer fevers. That vaccine, with its lower doses, had low effectiveness after two shots, but it might ultimately provide more protection after three shots, given omicron and its subvariants. Moderna is testing a third dose and says it will have results during the summer.

While most children don’t become seriously sick with covid, a small number develop severe illness, even though they do not have underlying medical conditions. More than 400 children younger than 5 have died from covid, the FDA said this week. Others who are infected risk developing long covid, a constellation of symptoms that can extend for months or years with long-term effects, including on brain development, that are still being studied. In addition, Besser said, vaccines will ease the stress of parents who worry: “What if it is my child who has that bad outcome?”

Studies have shown that immunity from infection with omicron does not last long, and the rate at which omicron subvariants have been evolving means new strains are able to infect people who have recently had a covid infection. Health and Human Services Secretary Xavier Becerra announced this week he had contracted covid for the second time in less than a month.

“In regards to education, it really is going to take an effort at the federal level, as well as at the state and local level,” said Lisa Costello, a member of the pediatric organization’s committee on state government affairs. “We know that pediatricians and health-care providers are trusted sources of information.”

Julia Skapik, chief medical information officer at the National Association of Community Health Centers, said many health professionals intend to have conversations about the vaccine with parents during regular office visits, because many parents are not planning to get their child vaccinated. It’s getting close to the time when schoolchildren need their annual physicals, and “that’s a real opportunity for getting kids vaccinated.”

Some parents have wondered whether babies younger than 6 months will be eligible for coronavirus vaccines at some point. Experts said some studies are underway but that the data is not yet available on whether a vaccine for that age group would be feasible or beneficial.

Some vaccines are not administered to infants because they have immature immune systems and therefore cannot generate a good immune response to a vaccine, said Inglesby of Hopkins. Babies also generally have their mother’s antibodies to protect them, Inglesby said.

Part of the reason is that the pediatric coronavirus vaccines, unlike the adult versions, ran into delays and setbacks, with the Pfizer-BioNTech vaccine initially planned as a two-shot vaccine regimen but failing to mount an effective shield for children 2 through 4 years old. The vaccine makers added a third shot to their trial, delaying vaccine availability by months.

“Once you have good results, without safety signals, you might want to think about doing things in a way that would include vulnerable groups, such as pregnant women and children, more quickly,” Permar said. Studies to determine the correct doses could be conducted on several age groups at once, she said.
