Information About the COVID-19 Vaccines

Getting vaccinated—including getting a booster shot—is the best way to protect yourself, your loved ones, and your community from COVID-19.

The Food and Drug Administration has granted full approval to the Pfizer-BioNTech COVID-19 vaccine for people ages 16 and older, and to the Moderna vaccine for those 18 and older. Children ages 5 to 15 may receive the Pfizer-BioNTech vaccine under emergency use authorization (EUA). Also under EUA, the Johnson & Johnson vaccine is available to those 18 and older.

The mRNA vaccines made by Pfizer-BioNTech and Moderna require two shots, normally given about three to four weeks apart. People who are considered severely immunocompromised are recommended to get a third shot as part of their primary series.

For continued protection, people ages 5 and up should then get a booster shot five months after the second dose (three months after the third dose for the severely immunocompromised). People ages 50 and up and people who are immunocompromised may wish to speak to their doctor about whether to get another booster at least four months after the first booster.

Vaccination Appointments

Patients ages 12 and up can use this link to make an appointment for a first dose or booster shot of the Pfizer-BioNTech vaccine at Mount Sinai. (Appointments for second doses will be made at the time you receive the first dose.)

Patients ages 5-11 can be scheduled for vaccination appointments through their doctor's office.

For information about vaccination through the Mount Sinai South Nassau Vaxmobile, please check Mount Sinai South Nassau’s Facebook page. For an appointment, please email Vaxmobile@snch.org.

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.

Patients ages 16 to 18 need parental/guardian consent for vaccination. Patients ages 5 to 15 must be accompanied by a parent or guardian.

People who are age 5 and older and who are moderately or severely immunocompromised are eligible for additional doses of an mRNA vaccine (Pfizer-BioNTech for ages 5 and up; Moderna only if 18 or over) as part of their primary series. This includes many people who are getting treatment for cancer, have had organ transplants, or receive treatments that weaken their immune systems. In addition, if you have received a bone marrow transplant or CAR-T therapy, you may need to repeat your vaccine series if you were vaccinated before receiving these treatments. If you are in one of these categories, please make an appointment through your doctor’s office. 

Everyone receiving a booster shot will need to bring their original vaccine card with them to their appointment.
