THE HAGUE, Netherlands — The European Union's drug regulator on Thursday authorized Pfizer's coronavirus vaccine for use on children from 5 to 11 years old, clearing the way for shots to be administered to millions of elementary school pupils amid a new wave of infections sweeping across the continent.
It is the first time the European Medicines Agency has cleared a COVID-19 vaccine for use in young children.
The agency said it "recommended granting an extension of indication for the COVID-19 vaccine Comirnaty to include use in children aged 5 to 11."
After evaluating a study of the vaccine in more than 2,000 children, the EMA estimated that the vaccine was about 90% effective in preventing symptomatic COVID-19 in young children and said the most common side effects were pain at the injection site, headaches, muscle pain and chills. The agency said the two-dose regimen should be given to children three weeks apart.

Europe is currently at the epicenter of the pandemic and the World Health Organization has warned the continent could see deaths top 2 million by the spring unless urgent measures are taken.
