COVID-19 Vaccination Information, Appointments and Resources

As of Monday, August 23, 2021, the Food and Drug Administration granted full approval to the Pfizer-BioNTech COVID-19 vaccine for people age 16 and older. It continues to be available under emergency use authorization (EUA) for people age 12 to 15, and for the administration of a third dose in certain immunocompromised people.

First Dose Appointment

If you are 12 or over and live in the United States, you can register for a vaccine (first dose) appointment here. If you prefer to make an appointment by phone, please call (646) 605-5764. We are also continuing to reach out directly to eligible patients and community members to offer vaccinations.

You can also check the New York State, New York City, New Jersey, or Connecticut websites for other locations that offer appointments or walk-in vaccination. New York City is also offering in-home vaccinations for all residents 12 and over, as well as mobile vaccination vans.

If you are seeking vaccination for a person younger than 18, make sure that the location you have chosen offers the Pfizer-BioNTech vaccine. Other vaccines are only authorized for people 18 and over.

Vaccination records from Mount Sinai are available through New York State’s digital app, Excelsior Pass. For more information, see FAQs below or visit the Excelsior Pass website.

Third Dose Appointment

People who are moderately or severely immunocompromised are eligible for an additional (third) dose of an mRNA vaccine. This includes many people who are getting treatment for cancer, have had organ transplants, or receive treatments that weaken their immune systems. See below for more information.

We are not able to offer third doses or additional doses to others at this time, as these have not been authorized by either the FDA or the CDC.

If you think you are eligible and have received two doses of the Pfizer vaccine, an appointment for a third dose at a Mount Sinai site can be made here.
