Ramped up vaccination efforts began Monday at a mass vaccination site at Stony Brook University, a site of confusion for some Long Island residents.

The site opened on the same day Gov. Andrew Cuomo delivered some alarming news to the region. Long Island's seven-day positivity rate is currently at 7.84%, about 2% higher than New York City.

The Stony Brook location will be able to accommodate 500 people a day, and possibly more as more supply is available.

As the numbers rise, residents are clamoring for vaccine appointments. The state gets about 300,000 doses a week, but Cuomo says there are now about 50,000 extra doses from people refusing to get vaccinated.

The current doses are mostly being prioritized for health care workers and elderly residents in long-term care facilities. Those extra doses will now be made available to others and sent to hospitals around that state that are quickly getting out doses.

"We want to make sure that the faster facilities, the higher performing facilities, get more of the new allocation because we want it out the door," says Cuomo. "We don't want it sitting on the shelf. So those that can vaccinate faster will get more of the new allocation."

Cuomo says the federal government created more demand by lowering the eligibility age to 65 but didn't increase any of the supply, adding to frustrations. The governor is now asking Pfizer to see if the state can buy the vaccine directly from the company.

In the meantime, there are groups of Long Islanders who thought they had a reservation at Stony Brook, but state officials ended up voiding them.

Dorthea Reiter says her teachers union sent her a link for a COVID-19 vaccine appointment, and she booked one for Feb. 14. But that was quickly taken off the books because the state ruled the link was invalid due to being leaked early.

Now Reiter's lost her place and doesn't know when she'll be able to get a shot.

"Why not simply honor those appointments? It doesn't make sense to me," she says. "I am frustrated, and I am disappointed, and I know I'm not the only one."
