MILWAUKEE— After the FDA gave them the green light earlier this week, the CDC appeared poised Tuesday to sign off on Pfizer's booster shot for kids between the ages of 12 and 15.

"Here in Dane County and this part of the state, this age group, 12-17, is heavily vaccinated, so we expect them to be back for their third shots [when approved]," said Mo Kharbat, the vice president of pharmacy services with SSM Health.

While the CDC Tuesday did approve bumping up the wait time for booster shots from six months to five months, booster shot availability for Americans as young as 12 is likely to come by the end of the week, and Kharbat said he knows certain families will line up for them quickly.

"Any time the booster or vaccine criteria expanded, we saw and uptick in them," Kharbat added. "We now know based on recent evidence that a booster shot strengthens the immune system to prevent infection from the Omicron variant."
