Monkeypox Vaccine Information

Mount Sinai Health System provides vaccination against monkeypox for eligible people. You don't need to be a Mount Sinai patient to schedule this vaccine at our clinics.

Monkeypox is an infectious disease that's currently spreading in the United States. It's transmitted through close contact and causes a rash on various parts of the body. You can learn more about monkeypox and what to do if you may have been exposed from New York City and the Centers for Disease Control and Prevention.

Vaccination Eligibility

If you have been exposed to monkeypox, getting vaccinated may keep you from getting sick. Vaccination is most effective within four days of exposure but can help up to 14 days later.

Vaccine is currently available for at-risk populations, defined by the New York City Department of Health and Mental Hygiene (DOHMH). To be eligible to receive the vaccine, you must meet both of the following criteria:

  • Gay, bisexual, or other man who has sex with men or transgender women; transgender, gender non-conforming, or gender non-binary; or a transactional sex worker of any sexual orientation or gender identity
  • Have had multiple or anonymous sex partners in the last 14 days

Monkeypox Vaccines at Mount Sinai Health System

Mount Sinai is currently able to offer first and second doses of the JYNNEOS™ vaccine to those who attest to meeting both of the eligibility criteria above. To check your eligibility and schedule a vaccination appointment at Mount Sinai, please click here. In accordance with DOHMH guidance, most patients will receive an injection just below the skin in your forearm, similar to a tuberculosis test. This is known as an “intradermal” injection. If there is a reason why you should not receive an intradermal injection, you will be asked about it before you receive the vaccine. Learn more about intradermal vaccination here.

Please note that vaccine supplies are very limited. If you are unable to get an appointment, check back periodically to see if more appointments have become available. You can also try the New York City vaccine site.

Please note that the city has now removed the age restriction for this vaccine. However, patients under 18 will need consent from a parent or legal guardian, and patients 15 and under must be accompanied by a parent or legal guardian.
