Vaccines

Mpox vaccination helps protect against mpox when given before or shortly after exposure. Two mpox vaccines are currently available in the United States via the Strategic National Stockpile. 

The federal government has allocated JYNNEOS vaccine to Californians. The California Department of Public Health (CDPH) is working with the Centers for Disease Control and Prevention (CDC) and California Local Health Departments to make this vaccine available to communities to provide protection against mpox.  

Although there are no longer any specific “eligibility” criteria for JYNNEOS vaccine, CDC​ and CDP​H continue to update recommendations for the prioritization of JYNNEOS vaccine among high-risk​ communities. Stay up to date on the latest information regarding vaccine strategies for mpox.
