Stony Brook University's COVID-19 vaccine site has hit a major milestone in the battle against the pandemic.

The state-run site reached its 25,000th vaccination Thursday, exactly a month after the site first opened.

Getting appointments at the state-run site has caused some headaches for Long Islanders over the past month, especially with a handful of winter storms canceling some vaccinations in recent weeks.

"The efficient and effective administration of the vaccine is an example of the excellent work the University and Stony Brook Medicine have been doing to help stop the spread of COVID-19 and bring this pandemic to an end," says University President Maurie McInnis.

Stony Brook University Hospital has also had a hand in launching pop-up vaccine sites aimed at helping vaccinate underserved communities.

All of New York's state-run vaccine sites remained opened Thursday amid the snowstorm.
