Monkeypox Vaccination

The virus that causes mpox is related to the virus that causes smallpox. JYNNEOS is a 2-dose vaccine developed to protect against mpox and smallpox. People need to get both doses of the vaccine for the best protection against mpox. The second dose should be given 4 weeks after the first dose. However, if it has been longer than 4 weeks since you got the first dose, get the 2nd dose as soon as possible. Whether or not you've been vaccinated, continue to reduce your risk of getting mpox
