How Vaccination Works
The JYNNEOS vaccine is administered in two doses, spaced 28 days apart. It provides the best protection against mpox when both doses are given, significantly reducing the risk of severe illness and hospitalization. Studies indicate that two doses can lower the risk of getting mpox by up to 86-89% . Even if infections occur post-vaccination, symptoms are typically milder than in unvaccinated individuals.
For those who have been exposed to mpox, vaccination is recommended as soon as possible, ideally within four days of exposure. The effectiveness of the vaccine decreases as the time since exposure increases, so prompt vaccination is crucial .
Who Should Get Vaccinated
Vaccination is particularly recommended for individuals at higher risk, such as gay, bisexual, and other men who have sex with men, transgender or nonbinary persons, and those who are immunocompromised or have certain health conditions. Pregnant women, young children, and those with advanced HIV infection are also at increased risk of severe disease and may be prioritized for vaccination in areas with community transmission [.
Public-Health Implications
While vaccination is effective in preventing mpox, it is not a substitute for other preventive measures. Individuals should continue to avoid close contact with those infected and follow public health guidelines to minimize risk. The approach to mpox vaccination emphasizes targeting high-risk groups rather than mass vaccination, ensuring that available vaccine stocks protect those most vulnerable .
This focused vaccination strategy matters for public health because it helps control outbreaks effectively while conserving resources for those who need them most. As part of a broader preventive approach that includes awareness and behavioral changes, vaccination plays a critical role in reducing the spread of mpox.
