As a result, the city is holding off on scheduling 30,000 to 35,000 appointments.
The shortage is due to the winter storms across the country delaying the vaccines' arrival.
So far, the city has administered 1,364,956 total doses of the COVID-19 vaccine. Mayor de Blasio says his goal, pending supply, would be to vaccine 500,000 New Yorkers a week.
Meantime, a new vaccination site opened Wednesday at Teachers Preparatory High School in Brownsville, Brooklyn.
It is for residents of the immediate neighborhood.
On Tuesday the city released data showing wealthier, predominately white neighborhoods with vaccine rates above 20 percent.
By contrast, in lower-income, black neighborhoods like East New York, Jamaica, and Bedford-Stuyvesant, just 3 percent of the population has gotten the first dose.

Those neighborhoods with low vaccination rates also tend to have higher rates of infection.
Mayor Bill de Blasio says the city is opening more vaccination sites in these neighborhoods to try to change that.
"We're going to be doing a lot of grassroots outreach to draw people from Brownsville and East New York to this center right in their community, to get the help that they need and deserve," the mayor said. "And grassroots outreach, grassroots leadership, is going to be key to getting this done."
The city also updated its vaccine scheduler in 10 different languages. You can visit nyc.gov/vax4nyc to make an appointment in New York City.
Mount Sinai Hospital announced Tuesday night that they were canceling some appointments to give out first doses of the vaccine because they were suddenly getting fewer doses from the city than promised.
NYU Langone said it is cutting back on the number of appointments they offer to give out the vaccine for the same reason.
Both the state and city are shifting resources to get vaccines into neighborhoods most in need.
