The Centers for Disease Control and Prevention is now recommending everyone 18 and older get a booster dose of a COVID-19 vaccine amid news of the omicron variant.

Doctors say more than a dozen people came to the Vax Mobile at Freeport High School Tuesday to get the vaccine.

Pfizer is also reportedly expected to seek approval to expand use of its vaccine to 16- and 17-year-olds. If granted emergency use authorization, the additional Pfizer dose would be the first available to anyone under 18.

Dr. Twana Jackson says they support making the booster available to younger people, but it's unclear what dose that age group would be given.

"The pediatric dose is one-third of the adult dose, we'll have to see," Jackson says. "A 16- and 17-year-old can have an adult body size so that is something that will be looked at."

Others say it's a great idea but aren't going to be getting their own children vaccinated.

"My son who is vaccinated, he's 18," says Smithtown resident Margaret Holiey. "I don't think he'd get the booster unless they require it at school."

The Vax Mobile will be at the courthouse Wednesday in Island Park.
