COVID-19 Vaccine Information

This Is Important

For the foreseeable future, everyone—including those who were vaccinated—must continue to practice protective behaviors including wearing a face covering, physical distancing, following testing protocols, avoiding nonessential travel, and other measures. This is important since it is not yet known if the vaccines protect against asymptomatic infection and consequently prevent transmission to others. In addition, it will take time to achieve high vaccine uptake (estimated at 70-80%) to achieve herd immunity, i.e., sufficient population-level protection from transmission of the virus.  

Frequently Asked Questions

Which vaccines have been authorized for use in the United States?

There are currently two vaccines that have received Emergency Use Authorization (EUA) by the U.S. Federal Drug Administration (FDA). These include the Pfizer BioNTech vaccine and the Moderna vaccine. Read more.

How do the Moderna and Pfizer vaccines work?

Both vaccines use genetic material known as messenger RNA that instructs the body's cells to make a protein that mimics the spike proteins found on the surface of the coronavirus. These vaccine-induced proteins then stimulate the immune system to produce antibodies to fight the virus. Read more.

When will the Pfizer and Moderna vaccines be available to the public and who will receive it first?

The vaccines are currently being distributed to various states. In New York City, at present prioritization of the vaccine will follow New York State and CDC guidance. Read more.
