News and Updates
- Mpox (formerly known as monkeypox), Updates, and Links
May 23, 2023
We believe and the science shows that one of the best ways to protect yourself against mpox is through vaccination. Mpox Vaccination is a 2-dose series with the second dose administered 28 days after the first dose. If you have received two doses of the mpox vaccine, you do not need to be vaccinated now. If, however, you have received one dose of the mpox vaccine, we recommend that you come in for your second dose. If you have not been vaccinated at all against mpox, we strongly recommend that you consider being vaccinated. People who live and/or work in Massachusetts who meet one or more of the following descriptions are eligible to receive the mpox vaccine:
- Gay, bisexual, and other men who have sex with men, transgender, gender non-conforming, or nonbinary people who:
- Have had a diagnosis of or have sought testing for one or more sexually transmitted diseases (i.e., chancroid, chlamydia, gonorrhea, or syphilis) in the past year
- Are living with HIV infection
- Are on or are eligible to be on HIV PrEP
- Have recently had more than one sex partner
- People who :
- Have had sex at a private or commercial sex venue (e.g. sex party. bathhouse)
- Have had sex in association with a large public event (e.g. rave, circuit party) in a geographic area where mpox transmission is occurring
- Sexual partners of people with the above risks
- People who anticipate experiencing the above risks
