LOUISVILLE, Ky — The top doctor at UofL Health explained how new findings from Pfizer are promising, but not official policy yet.

Chief Medical Officer Dr. Jason Smith announced Wednesday that Louisville's Cardinal Stadium will become the commonwealth largest vaccination site. At the announcement, Spectrum News 1 asked for his reaction to Pfizer's announcement  that it believed its vaccine was safe for children as young as 12.

"Right now it's at 16 and over. That's the simple fact from Pfizer," he said. "I do expect, at some point in time, that we will be administering this vaccine to basically most children once we continue and complete those trials,"

The trials he addressed were conducted by Pfizer and, according to the company, recorded zero positive cases for the novel coronavirus in more than 2,200 US volunteers, ages 12-to-15, who were given the vaccine.

"I think this will be part of ongoing vaccination efforts that we do for kids who wind up going to school and getting other vaccines for needing to go to school from that standpoint."

It is not yet clear how quickly the FDA would act on Pfizer's request to allow vaccination starting at age 12.
