Pfizer says Covid-19 vaccine more than 90% effective in kids

Pfizer says kid-size doses of its Covid-19 vaccine are safe and nearly 91 percent effective at preventing infections in elementary school children. It can protect from 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 shots could begin early next month — with the first children in line fully protected by Christmas — if regulators give the go-ahead.

Details of Pfizer’s study were posted online on Friday. Advisers to the Food and Drug Administration will publicly debate the evidence next week.
