(AP/WTNH) — The U.S. Food and Drug Administration is expected to authorize Pfizer’s COVID-19 vaccine for kids ages 12 to 15 by next week, setting up shots for many before the beginning of the next school year.

That’s according to a federal official and a person familiar with the process.

According to ABC News, experts have said vaccinating younger populations is critical because even though they are less likely to get seriously ill –they can still get and spread COVID to others, especially when indoors, close together, interacting with people outside of their homes.

The FDA action would be followed by a meeting of a federal vaccine advisory committee to discuss whether to recommend the shot for 12- to 15-year-olds.

Then, the Centers for Disease Control and Prevention would act on the committee’s recommendation. Those steps could be completed in a matter of days.

Right now, people 16 and older are approved to get the Pfizer COVID vaccine.

Connecticut is now the first state in the county to have half of its adults fully vaccinated against COVID-19, with 69% of adult residents receiving their first dose. Governor Ned Lamont hopes to reach 80% of residents with their first dose, in an effort to reach herd immunity.

Meanwhile, the Pfizer vaccine is currently in trials at Yale on kids as young as 6 months old.
