People with HIV are over-represented in current mpox cases. We do not know if having HIV increases the likelihood of getting infected with monkeypox virus (MPXV) if exposed, however, we do know that people with advanced HIV (immunocompromised) are at increased risk of severe mpox and death if they get mpox. Learn more about how mpox spreads.

If you have HIV, you should follow the same recommendations as everyone else to protect yourself from mpox, including getting vaccinated. Taking your HIV medication as prescribed and keeping an undetectable viral load are the best things you can do to stay healthy and doing so also prevents you from sexually transmitting HIV to your HIV-negative partner.

Mpox Vaccines and People with HIV

JYNNEOS is a two-dose vaccine, authorized for the prevention of mpox and is considered safe and effective for people with HIV. This is the vaccine currently being offered in the United States.

Learn more about who should get vaccinated and talk to your health care provider about getting vaccinated against mpox.

You may have heard of mpox vaccine PEP. This can be confusing because we use the term HIV PEP in HIV prevention as well. Here’s a simple explanation of what they mean:

  • HIV PEP (post-exposure prophylaxis) is medicine that can reduce your chances of getting HIV after a possible exposure to the virus.
  • Similarly, mpox vaccine PEP is when you get the mpox vaccine to reduce your chances of getting mpox after a possible exposure to MPXV.

Getting Mpox When You Already Have HIV

  • Limited data suggest that people with HIV, particularly people with low CD4 counts (<350 cells/ml) or who are not virally suppressed, are more likely to be hospitalized and possibly die if they get mpox than people without HIV.
  • Mpox treatments are safe and may be used to treat people who are more likely to get severely ill with mpox. If you have HIV, ask your healthcare provider about what treatment options you should consider.
  • Based on what we know, mpox treatments have very few possible interactions with HIV medicines. If you have HIV, let your health care provider know before starting mpox treatment.
  • HIV pre-exposure prophylaxis (PrEP)and HIV post-exposure prophylaxis (PEP) are still effective for preventing HIV even if you have mpox or are taking mpox treatment. If you have been prescribed HIV PrEP or HIV PEP by your health care provider, you should continue taking your medicine as prescribed.
