The mad dash is on for Long Island residents trying to get the COVID-19 vaccine with eligibility now open to those 30 and older.

Gov. Andrew Cuomo's office says the new eligibility means over 2 million New Yorkers who weren't previously able to get the vaccine are now in the mix.

It was a busy afternoon at Vanco Pharmacy in Commack. The store just got 200 doses of the Johnson & Johnson vaccine. Last week, it got no vaccines but took down names and numbers.

People like Steven Chiappetta from Dix Hills put his name on the location's waiting list last week, and got the shot Tuesday.

"My wife called me and said, 'Steven I just got the call and you're going to be able to go next week.' It's fantastic and just a breath of fresh air. A big weight off my shoulders," says Chiappetta.

Tuesday's opening is just a preview for what's sure to be an even bigger dash that comes when doses can be given to those 16+ next week.

"It's a juggling act because it changes so fast," says Glenn O'Kane, of Vanco Pharmacy. "Whatever was the policy yesterday may not be tomorrow."

But worries remain over whether supply can keep up with the increasing demand. Local officials are adamant it will improve in the next few weeks.

"We're still not at the sweet spot where supply and demand are matching," says Nassau Executive Laura Curran. "We still have more demand than we do have supply, but we know that's going to change very, very quickly. I am a big fan of opening up the eligibility, I think that was exactly the right move."
