Pfizer says its vaccine is 90.7% effective against symptomatic COVID-19 in children ages 5 to 11

(CNN) – New papers released ahead of a key meeting of U.S. Food and Drug Administration vaccine advisers, Pfizer said its vaccine is safe and 90.7% effective against symptomatic COVID-19 in children ages 5 to 11 years.

In the trial, which included about 2,000 children, there were three cases of Covid-19 in the group that received the vaccine and 16 cases in the placebo group. In the trial, twice as many children received the vaccine as the placebo.

Pfizer / BioNTech is requesting emergency use authorization from the FDA for a two-dose regimen of its 10-microgram dose for children 5 to 11 years of age. The two doses will be administered three weeks apart.
