Jynneos is a vaccine that provides protection against both smallpox and monkeypox viruses. It is a live, non-replicating vaccine that works by stimulating the body’s immune system to produce antibodies against these viruses. This vaccine is administered as a two-dose series, with the second dose given 4 weeks after the first.

Jynneos is recommended for individuals who are at high risk of exposure to smallpox or monkeypox, such as healthcare workers, laboratory personnel, and military personnel. It is also recommended for individuals who are traveling to areas where these viruses are endemic.

Like all vaccines, Jynneos may cause side effects in some individuals. Common side effects include pain, redness, and swelling at the injection site, as well as fever, headache, and muscle aches. These side effects are usually mild and go away on their own within a few days.

It is important to discuss with your healthcare provider if Jynneos is right for you, especially if you have a weakened immune system or if you are pregnant or breastfeeding. Your healthcare provider can help you weigh the risks and benefits of the vaccine and determine the best course of action for your individual situation.

Overall, Jynneos is a safe and effective vaccine that can provide important protection against smallpox and monkeypox viruses. By getting vaccinated, you can help protect yourself and others from these potentially serious infections.
