Pfizer says child-sized doses of the Covid-19 vaccine are safe and approximately 91% effective in preventing infection in primary school children.

Details of the study were released online Friday as US regulators consider opening vaccinations to young adults from 5 to 11 years old.

Snaps could begin early next month – with the first children fully protected by Christmas – if organizers give the go-ahead.

The Food and Drug Administration is expected to publish its preliminary review of the company’s safety and efficacy data later Friday. Next week, FDA advisors will publicly discuss the evidence.

If the FDA then allows lower doses, the Centers for Disease Control and Prevention will make final recommendations on who should receive them.

Pfizer’s full-strength injections have already been authorized for anyone 12 or older, but pediatricians and many parents are eagerly waiting to protect younger children to stop the rising infection of the highly contagious delta variant and help keep kids in school.
