The U.S. Food and Drug Administration's vaccine advisory committee is meeting on Friday to vote on whether to approve a booster shot for the Pfizer-BioNTech COVID-19 vaccine.
It could mean more fully-vaccinated people might be thinking about a third dose, just as they should also be getting a flu shot.
There has been some confusion and debate about boosters.
"Anybody should get vaccinated period," she said. "So if you haven't even received a first dose, you're able to get a first dose then second dose 90 days after you are diagnosed with a COVID-19 infection."
If you're vaccinated and got a breakthrough case, Kotis said you should still get a booster if and when it is recommended for you.
If you're eligible for a third COVID shot soon — you could get your flu shot at the same time.
"I would recommend getting your flu shot and getting your COVID (shot) assuming the booster data's there," she added. "If you're in the group that the CDC recommends, yes, get your COVID booster. Do not wait."
