Information About the COVID-19 Vaccines

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

The vaccines currently authorized for use are known as “bivalent” vaccines because they offer increased protection against two subtypes of the virus. Recommendations for these vaccines are as follows:

If you are unvaccinated, partially vaccinated, or have only received the original “monovalent” vaccine:

  • Six years and up: One dose of bivalent vaccine
  • Six months to five years: One to three doses of bivalent vaccine, as recommended by your child’s pediatrician
  • Patients who are immunocompromised (all ages): Speak to your doctor about whether you should get additional doses of vaccine

If you have previously received at least one dose of bivalent vaccine:

  • If you are 65 or older, a second dose of bivalent vaccine is recommended at least four months after your initial dose
  • If you are immunocompromised, speak to your doctor about whether additional doses are recommended
  • If you are under 65 and not immunocompromised, no additional doses are recommended at this time

All Mount Sinai patients, including children, can be scheduled for a bivalent COVID-19 vaccine through their doctor's office. We are also offering bivalent vaccines on a walk-in basis at the Mount Sinai-Union Square Urgent Care location, Monday-Friday from 8 am to 7 pm.
