The city is also doubling appointments at Teacher's Prep and Martin Van Buren sites because the city's vaccine supply has increased.
There are also pop-up sites opening at First Corinthians Baptist Church in East Harlem and Mill Basin.

Mayor de Blasio also announced that faith communities would open up pop-up sites, just as Reverend Al Sharpton and 10 pastors got vaccinated at Harlem Hospital.
He said his goal was to try to increase testing and vaccine awareness.
"We want to set an example to our community," Rev. Sharpton said. "I'm here saying I cannot afford not to take the shot."
Mayor de Blasio asked him why he personally chose to have the shot and how he felt.
"I personally took the shot because I feel two things; one, you have got to be sure that your loved ones and people you are around are not risking themselves being around you because you are playing some jaded game of Russian roulette saying, I may be still negative, I may not be. That's not fair to your loved ones even if you want to do that to yourself," Rev. Sharpton said. "And secondly, is that I wanted to set an example. I think those of us that are in the public ought to set a public example, and I didn't want to tell people to go do something that I would not go do myself."
Sharpton added that he was feeling well and did not feel any after-effects of the vaccine as of yet.
