Monkeypox Vaccine

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.

CDC recommends vaccination against monkeypox if:

• You had known or suspected exposure to someone with mpox
• You had a sex partner in the past 2 weeks who was diagnosed with mpox
• You are a gay, bisexual, or other man who has sex with men or a transgender, nonbinary, or gender-diverse person who in the past 6 months has had any of the following:
  • A new diagnosis of one or more sexually transmitted diseases (e.g., chlamydia, gonorrhea, or syphilis)
  • More than one sex partner
• You have had any of the following in the past 6 months:
  • Sex at a commercial sex venue (like a sex club or bathhouse)
  • Sex related to a large commercial event or in a geographic area (city or county for example) where mpox virus transmission is occurring
• You have a sex partner with any of the above risks
• You anticipate experiencing any of the above scenarios
• You are at risk for occupational exposure to orthopoxviruses (e.g., certain people who work in a laboratory or a health care facility).
