Family members look on as Jack Frilingos, 12, is inoculated with Pfizer's vaccine against coronavirus disease (COVID-19) after Georgia authorized the vaccine for ages over 12 years, at Dekalb Pediatric Center in Decatur, Georgia, U.S. May 11, 2021.
REUTERS/Chris Aluka Berry/File PhotoPfizer Inc (PFE.N) said on Tuesday it will start a large study to test its COVID-19 vaccine in children below 12 and selected a dosing regime for the trial.
The study will enroll up to 4,500 children at more than 90 clinical sites in the United States, Finland, Poland and Spain, the company said.
Pfizer's vaccine has been authorized for use in children as young as 12 in Europe, the United States and Canada.
Inoculating children and young people is considered a critical step toward reaching "herd immunity" and taming the COVID-19 pandemic.
