Available to people of any age or gender who may have been exposed. Make an appointment today at

Some providers may also have a supply of vaccines for their eligible patients. Please contact your provider for more information.

Vaccines help protect against monkeypox when given before or shortly after exposure to the virus. The JYNNEOS vaccine is approved by the U.S. Food and Drug Administration (FDA) to prevent both monkeypox and smallpox. It is most effective at preventing monkeypox if the vaccine is administered within 4 days of exposure. When given between 4-14 days after the date of exposure, vaccination may help reduce symptoms but may not prevent the disease from developing.

Vaccine Eligibility

Vaccine supply has increased. Vaccines are now available for anyone who may be at risk and anyone who wants to get vaccinated.

Certain groups are especially recommended to get vaccinated. These groups are:

  • Anyone living with human immunodeficiency virus (HIV), especially those with a CD4 count <350/mm3, an unsuppressed HIV viral load, or an opportunistic infection.
  • Any man or trans person who has sex with men or trans persons
  • People who use or are eligible for HIV PrEP
  • Sex workers
  • Sexual partners of the above groups
  • People who have had direct skin-to-skin contact with one or more people AND who know others in their community that have had MPX infection
