Two new mega vaccine sites that were slated to open this week are now being put on hold due to the vaccine shortages in the city.

Yankee Stadium and Citi Field are two of those huge venues that would have provided the space for vaccinations if the supply was there.

Mayor Bill de Blasio announced earlier that the city has the ability to vaccinate 500,000 people per week.

The city confirmed to News 12 that in order for the mega sites to open, there would need to be a supply of 200,000 doses every week.

The city currently has under 20,000 first doses on hand, and is expected to get 107,000 more in the next few days.

The city and state are waiting for more details from the Biden administration as to when the federal government will be able to get more vaccines to New York.

De Blasio says the administration is incredibly focused and they are in constant communication.

The mayor says the mega sites could be very helpful, but in order for them to work they need more vaccines and flexibility with the current supply.

“We don’t have the supply ready to go we want,” de Blasio says.

More than 628,000 doses have already been given, and the mayor says that is already more than the entire population of Louisville, Kentucky.
