Teen COVID boosters approved by US drug agency

Washington: All teenagers in the US will soon be eligible for COVID boosters after the Food and Drug Administration allowed extra Pfizer shots for children as young as 12.

Boosters are already recommended for everyone 16 and older and American regulators have now decided they’re also warranted for 12 to 15-year-olds once enough time has passed since their last dose.

But the move, coming as schools restart after the holidays, isn’t the final step. A panel to the Centres for Disease Control and Prevention is expected to decide later this week whether to recommend boosters for the younger teens with a final decision to be made by Dr Rochelle Walensky, the centre’s director.

The FDA also said everyone 12 and older who’s eligible for a Pfizer booster can get one as early as five months after their last dose rather than six months.

The agency’s vaccine chief Dr Peter Marks said even though serious illness was uncommon in younger teens, a booster would help them avoid that risk — while also helping reduce the spread of Omicron or any other coronavirus mutant.

“Hopefully this will be not just a call for people to go get their booster shot,” but for the tens of millions of unvaccinated Americans to rethink that choice, Marks said. “It’s not too late to start to get vaccinated.”

The FDA based its latest booster decision largely on real-world data from Israel that found no new safety concerns when 6300 12 to 15-year-olds got a Pfizer booster five months after their second dose.

Likewise, the FDA said even more data from Israel showed no problems with giving anyone eligible for a Pfizer booster that extra dose a month sooner than the six months that until now has been US policy.

The chief safety question for younger teens is a rare side effect called myocarditis, a type of heart inflammation seen mostly in younger men and teen boys who get either the Pfizer or Moderna vaccines. The vast majority of cases are mild — far milder than the heart inflammation caused by COVID — and they seem to peak in older teens, the 16- and 17-year-olds.

Marks said the side effect occurs in about 1 in 10,000 men and boys aged 16 to 30 after their second shot — but that a third dose appears less risky, by about a third. That’s probably because more time has passed before the booster than between the first two shots, he said.

Vaccines still offer strong protection against serious illness from any type of COVID. But health authorities are urging everyone who’s eligible to get a booster dose for their best chance at avoiding milder breakthrough infections from the highly contagious Omicron mutant.

Children tend to suffer less serious illness from COVID than adults. But child hospitalisations are rising during the Omicron wave – most of them unvaccinated.

Paediatrician and global health expert Dr Philip Landrigan of Boston College welcomed the FDA’s decisions, but stressed that the main need is to get the unvaccinated their first shots.

“It is among unvaccinated people that most of the severe illness and death from COVID will occur in coming weeks,” he said in an email. “Many thousands of lives could be saved if people could persuade themselves to get vaccinated.”

The vaccine made by Pfizer and its partner BioNTech is the only US option for children of any age. About 13.5 million 12- to 17-year-olds — just over half that age group — have received two Pfizer shots.

For families hoping to keep their children as protected as possible, the booster age limit raised questions.

The older teens, 16- and 17-year-olds, became eligible for boosters in early December. But original vaccinations opened for the younger teens, those 12 to 15, back in May. That means those first in line in the spring, potentially millions, are about as many months past their last dose as the slightly older teens.

As for even younger children, kid-size doses for 5 to 11-year-olds rolled out more recently, in November – and experts say healthy youngsters should be protected after their second dose for a while. But the FDA also said Monday that if children that young have severely weakened immune systems, they will be allowed a third dose 28 days after their second. That’s the same third-dose timing already recommended for immune-compromised teens and adults.

Pfizer is studying its vaccine, in even smaller doses, for children younger than 5.
