FDA expected to approve Pfizer vaccine for ages 12 and up Officials say if it's approved, the hope would be to get as many kids vaccinated as possible before the start of the school year. Author: Leanne Stuck Updated: 11:18 PM EDT May 4, 2021 BUFFALO, N.Y. — Another big vaccination milestone is on the way. Next week, the U.S. Food and Drug Administration is expected to authorize the use of the Pfizer vaccine for kids as young as 12. NBC News Medical Contributor Dr. Kavita Patel gave 2 On Your Side some insight into the trials done on children. "It's great news," she said. "We know thousands of children aged 12 to 15 who were in the trial had very few side effects, no serious adverse events and 100% efficacy. And we have this by press release, we are waiting for the full data but the FDA should be making a decision soon and literally within days we would have this available for ages 12 to 15."
