The US has moved a step closer to expanding COVID vaccinations for millions more children as a panel of government advisers endorsed children-sized doses of Pfizer’s shots for 5- to 11-year-olds.
A Food and Drug Administration advisory panel voted unanimously on Tuesday (local time), with one abstention, that the vaccine’s benefits in preventing COVID-19 in that age group outweighed any potential risks – including a heart-related side effect that’s been very rare in teens and young adults despite their use of a much higher shot dose.
While children are at lower risk of severe COVID-19 than older people, ultimately many panellists decided it was important to give parents the choice to protect their youngsters – especially those at high risk of illness or who live in places where other precautions, like masks in schools, aren’t being used.
The virus is “not going away. We have to find a way to live with it and I think the vaccines give us a way to do that,” FDA adviser Jeannette Lee of the University of Arkansas said.
“I do think it’s a relatively close call,” said adviser Dr Eric Rubin of Harvard University.
“It’s really going to be a question of what the prevailing conditions are but we’re never going to learn about how safe this vaccine is unless we start giving it.”
The FDA isn’t bound by the panel’s recommendation and is expected to make its own decision within days.
If the FDA authorises the kid-size doses, there’s still another step: Next week, the US Centres for Disease Control and Prevention will have to decide whether to recommend the shots and which youngsters should get them.
Full-strength shots made by Pfizer and its partner BioNTech already are recommended for everyone 12 and older but paediatricians and many parents are clamouring for protection for younger children.
The extra-contagious Delta variant has caused an alarming rise in paediatric infections – and families are frustrated with school quarantines and having to say no to sleepovers and other rites of childhood to keep the virus at bay.
States are getting ready to roll out shots for little arms – in special orange-capped vials to distinguish them from adult vaccine – as soon as the national government gives the OK. More than 25,000 paediatricians and other primary care providers have signed up to offer vaccination.
While there is less COVID-19 among 5- to 11-year-olds, they still have faced substantial illness – including more than 8300 hospitalisations reported across the US, about one-third requiring intensive care, and nearly 100 deaths.
A study of primary schoolchildren found the Pfizer shots are nearly 91 per cent effective at preventing symptomatic infection – even though the youngsters received just one-third of the dose given to teens and adults.
Pfizer’s study tracked 2268 children ages 5 to 11 who got two shots three weeks apart of either a placebo or the kid dose. Vaccinated youngsters developed levels of virus-fighting antibodies just as strong as teens and young adults who got the full-strength shots.
The child dosage also proved safe, with similar or fewer temporary side effects – such as sore arms, fever or aches – that teens experience. At the FDA’s request, Pfizer more recently enrolled another 2300 youngsters into the study, and preliminary safety data has shown no red flags.
The study isn’t large enough to detect any extremely rare side effects, such as the heart inflammation that occasionally occurs after the second dose, mostly in young men and teen boys.
