On this page, you can find information on mpox vaccines and vaccine locations across the State of New Jersey. This page will be updated when new vaccination sites become available.
For New Jersey residents with known exposure to a person with mpox, the two-dose regimen for preventing mpox continues to be available through their local health department.
People who don’t have a known exposure, but have been in or may be in situations with a higher risk of exposure are eligible to receive the vaccine through what is known as Expanded Vaccination.
NJDOH receives mpox vaccines from the federal government and they are provided at no cost to eligible people.

About the vaccines
The preferred vaccine to prevent mpox is JYNNEOS
JYNNEOS is a two-dose vaccine administered 28 days (4 weeks) apart.
It takes 14 days after getting the second dose of JYNNEOS for its immune protection to reach its maximum.
People are considered fully vaccinated two weeks after receiving their second dose of the JYNNEOS vaccine.
JYNNEOS Frequently Asked Questions
The ACAM2000 vaccine is a single-dose alternative to JYNNEOS.
ACAM2000 takes four weeks after vaccination for its immune protection to reach its maximum.
ACAM2000 has the potential for more side effects and adverse events than JYNNEOS. It is not recommended for people with severely weakened immune systems and several other conditions.
Fully vaccinated people are still recommended to protect themselves against mpox and to isolate at home in case of symptoms.
