Monkeypox (orthopoxvirus) is a rare disease that is caused by infection from the Monkeypox virus. The Monkeypox virus is part of the same family of viruses that cause Smallpox. However, symptoms of Monkeypox are considered milder than those of Smallpox. The United States Center for Disease Control and Prevention (CDC) now recommends the Smallpox/Monkeypox Vaccine (JYNNEOS™) for people ages 18 and older that are at a high risk of contracting the Monkeypox virus.

What is the JYNNEOS™ Smallpox/Monkeypox Vaccine?

The JYNNEOS™ vaccine can prevent Monkeypox, Smallpox, Vaccinia, and other diseases caused by Orthopoxviruses. JYNNEOS™ is also approved by the United States Food and Drug Administration (FDA) for the prevention of Monkeypox and Smallpox infections. The CDC recommends the JYNNEOS™ vaccine for adults over the age of 18 that are at increased risk of contracting the virus. The CDC also recommends that certain laboratory workers and emergency response team members who might be exposed to viruses that cause orthopoxvirus infections.

 How does the JYNNEOS™ Smallpox/Monkeypox Vaccine work?

The JYNNEOS™ vaccine has been approved by the CDC for the prevention of Monkeypox and Smallpox. The vaccine contains the Vaccinia virus, which is a virus related to the Monkeypox and Smallpox viruses, that has been weakened, cannot copy itself in human cells, and cannot spread to other parts of the body or other people.

Health officials believe this vaccine can help protect people against Monkeypox when given before exposure to the virus. It can also reduce the risk of infection if given within four days after exposure to the Monkeypox virus, and reduce the risk of serious illness if given within 14 days after exposure to the Monkeypox virus.

How many doses of the JYNNEOS™ Vaccine do I need?

The JYNNEOS™ vaccine is administered in two doses. People should get the second dose of the vaccine at least 4 weeks after the first dose. A person will start building immunity in the days after their first dose and will not have complete immunity from the vaccine until about two from the second dose of the JYNNEOS™ vaccine. It is okay to wait more than 4 weeks to receive the second dose of the JYNNEOS™ vaccine. Currently, New York City is delaying the administration of the second dose of the JYNNEOS™ vaccine to ensure more people receive their first dose and have some protection from the Monkeypox virus. Once you receive your first dose your healthcare provider will inform you when you will qualify for the second dose of the vaccine.

How well does the JYNNEOS™ vaccine work?

    Clinical trial data show that the vaccine should be effective in preventing Monkeypox. There currently is no real-world data on the vaccine’s effectiveness and how well it prevents against the Monkeypox virus in the current outbreak. For this reason, it is important to continue other preventative measures such as avoiding intimate and physical contact with people who have symptoms of the Monkeypox virus even after you have been vaccinated. It is also recommended that you get tested for Monkeypox virus if you are experiencing any of its symptoms after you have been vaccinated.

If you suspect you have Monkeypox, the CDC recommends that you:

  • Contact your healthcare provider immediately.
  • Isolate yourself at home and avoid public gatherings.
  • If you have an active rash or other symptoms, stay in a separate room or area away from people or pets that live with you, if possible.

** If you are experiencing any of these symptoms and suspect you may have been exposed to Monkeypox, please contact your healthcare provider immediately.
