Kid-size doses of Pfizer’s COVID-19 vaccine appear safe and nearly 91% effective at preventing symptomatic infections in 5- to 11-year-olds, according to study details released Friday as the U.S. considers opening vaccinations to that age group.
The Biden administration has purchased enough kid-size doses — in special orange-capped vials to distinguish them from adult vaccine — for the nation’s roughly 28 million 5- to 11-year-olds. If the vaccine is cleared, millions of doses will be promptly shipped around the country, along with kid-size needles.
A Pfizer study tracked 2,268 kids in that age group who got two shots three weeks apart of either a placebo or the low-dose vaccine. Each dose was one-third the amount given to teens and adults.
Researchers calculated the low-dose vaccine was nearly 91% effective, based on 16 COVID-19 cases in youngsters given dummy shots versus three cases among vaccinated children. There were no severe illnesses reported among any of the youngsters, but the vaccinated ones had much milder symptoms than their unvaccinated counterparts.
Pfizer’s study of younger kids found the low-dose shots proved safe, with similar or fewer temporary side effects such as sore arms, fever or achiness that teens experience.
While children run a lower risk of severe illness or death than older people, COVID-19 has killed more than 630 Americans 18 and under, according to the CDC. Nearly 6.2 million children have been infected with the coronavirus, more than 1.1 million in the last six weeks as the delta mutant surged, the American Academy of Pediatrics says.
The shots could begin in early November — with the first children in line fully protected by Christmas — if regulators give the go-ahead.
