Gov. Andrew Cuomo gave New Yorkers a sneak peek during his briefing Thursday at what the Pfizer vaccine will look like when it is expected to arrive in the state on Dec. 15.

The Moderna vaccine is expected a week later.

With a sample box in front of him, the governor explained that each box Pfizer ships will contain about 5,000 vaccine dosages. Those boxes can only be opened twice, and for less than 90 seconds at a time.

They must be stored at 94 degrees, far lower than what the Moderna and AstraZeneca vaccines need to be stored at.

"We are working very hard to get ready for the distributions and training people on the distribution to make sure it's all done correctly,” said Gov. Cuomo, who called the vaccine “the light at the end of the tunnel.”

Earlier Thursday, Mayor Bill de Blasio said that the city is working with the state on a distribution plan, focusing on those with the greatest need for the vaccine to get it first, such as health care workers and nursing home residents and staff.

Another focus will be the neighborhoods that were hit the hardest by the coronavirus, particularly Black and brown communities.

The mayor said that public trust in the vaccine remains a challenge, adding that a campaign will be launched to inform New Yorkers about the vaccine.

He says a vaccine will be crucial to ending the pandemic once and for all.
