CBS Boston – Pfizer says that its COVID-19 vaccine is 100-percent effective in children ages 12 to 15.

Right now their two-shot vaccine is approved for people 16 and older. But the company now hopes to expand that to ages 12 and up after preliminary results from this small study.

Pfizer said 2,260 children ages 12 to 15 took part in the phase three trial. The company said preliminary data shows 18 cases of COVID-19 in the placebo group and zero cases in the vaccinated group.

“We plan to submit these data to FDA as a proposed amendment to our Emergency Use Authorization in the coming weeks and to other regulators around the world, with the hope of starting to vaccinate this age group before the start of the next school year,” Pfizer CEO Albert Bourla said in a statement Wednesday.

“We knew Pfizer did very well starting at age of 16 and now they’re telling us the response is even better in children 12 to 16 which I think is excellent news,” Dr. Rick Malley, a physician in the Division of Infectious Diseases at Boston Children’s Hospital, told WBZ-TV.

He is eager to see the specifics of the study, but he says Wednesday’s announcement is exciting.
