Mpox (formerly known as monkeypox) is caused by a virus that is related to the virus that causes smallpox. JYNNEOS is a two-dose vaccine developed to protect against mpox and smallpox infections.

People need to get both doses of the vaccine for the best protection against mpox. The second dose should be given four weeks after the first dose.

Vaccination is an important tool in stopping the spread of mpox. People who are vaccinated should continue to avoid close, skin-to-skin contact with someone who has mpox.

 

CDC recommends vaccination against mpox if: 

• You had known or suspected exposure to someone with mpox.
• You had a sex partner in the past two 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 six 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 six 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.
  • Sex in exchange for money or other items.
• You have a sex partner with any of the above risks.
• You anticipate experiencing any of the above scenarios.
• You have HIV or other causes of immune suppression and have had recent or anticipate future risk of mpox exposure from any of the above scenarios.
• You work in settings where you may be exposed to mpox:
  • You work with orthopoxviruses in a laboratory.

 

You should NOT get the vaccine if: 

You had a severe allergic reaction (such as anaphylaxis) after getting your first dose of the JYNNEOS vaccine.

 

You should take extra caution if:

You had an allergic reaction to any vaccine. You may still be vaccinated with JYNNEOS, but your provider may need to observe you for 30 minutes after you get vaccinated to make sure you don’t develop an allergic reaction.

Talk to your healthcare provider if you had an allergic reaction to the antibiotics gentamicin or ciprofloxacin, or chicken or egg protein.
