Three small doses of Pfizer and BioNTech's COVID-19 vaccine proved more than 80% effective at eliciting a strong immune response in children between the ages of 6 months and 5 years old, the companies said in a release this morning.
Why it matters: Pfizer is seeking an emergency use authorization to vaccinate children in this age group — one of the last groups of Americans still largely ineligible to receive a coronavirus shot. The companies said they will submit the trial data to the FDA this week.
