Nearly 300 people, most between the ages of 12 to 18, received their dose of Pfizer’s coronavirus vaccine Sunday in Bedford Hills.

Northwell Health set up the pop-up clinic at the former Pier 1 Imports store where they administered doses of the Pfizer vaccine.

Younger New Yorkers are receiving the vaccine following the recent emergency authorization approval given by the Food and Drug Administration and the Centers for Disease and Control Prevention.

Doctors are making it a point to get as many children vaccinated as possible as they are just as likely to contract and spread the virus as adults.

"At this age, they're very much into being with friends, and we think in order for them to be comfortable to return to school and not be afraid of possibly getting sick, I think it's critical," said Northwell Nurse Practitioner Marcia Dure.

Pfizer also plans to seek emergency approval to administer the vaccine to children as young as two.

Doctors says the vaccine is 100% effective against COVID hospitalizations and deaths in the 12 to 15 age group.

Vice President of Operations at Northwell Jeffrey Meade said this is a huge first step in helping fight back against the pandemic.

"You know, it's hard on everybody, but I think it's harder on them to not be able to live their lives normally. The more we get vaccinated throughout the entire population, the better, but I think in those age groups it's very important," he said.

Northwell Health, the largest health care system in the state, has already administered 450,000 doses of the vaccine since December.

"Northwell Health has been involved in vaccinating throughout the New York metropolitan area, and we've had a number of sites here in Westchester but none on a permanent basis. So this site gives us that permanent location," Meade said.

Parents and kids at the vaccination site said they are all on board.

"I feel it's important to get it so things can start to open up again," said Rosie Johnson, of Katonah.

"I think the vaccine is safe. It'll be a good protection for them, for their friends, they can get some... return to normalcy," said Pound Ridge resident Anthony Wong.
