Protect yourself by getting both doses of the mpox vaccine! 

Vaccination is recommended to protect Californians who may be at risk for mpox. The vaccine is safe and effective at preventing severe mpox illness and reducing chance of infection from both clade I and clade II mpox.

Mpox (formerly known as monkeypox) has been in the U.S. since 2022 and continues to circulate in California. To learn more about mpox, see CDPH Mpox Homepage​​. ​

Who should get the mpox vaccine? 

The California Department of Public Health (CDPH) recommends* the mpox vaccine (JYNNEOS) for any person who: 

  • ​​Is gay, bisexual, or other man who has sex with men or 
  • Is transgender, nonbinary, or gender-diverse or 
  • Has HIV, or is taking/eligible for HIV PrEP or doxy PEP​ or 
  • Was exposed to someone with mpox in the last 14 days or 
  • Is planning to travel to sub-Saharan Africa, the Middle East, or a country with a clade I mpox outbreak and anticipates sexual or intimate contact while traveling or 
  • Anticipates attending a commercial sex event or venue (like a sex club or bathhouse) or 
  • Has a sex partner with any of the above risks or 
  • Requests mpox vaccination, even if they have not disclosed any risks listed above 

In addition, the mpox vaccine is recommended for anyone at occupational risk for exposure to mpox​ (e.g., certain laboratory workers). 

*These recommendations are intended to simplify risk assessment and increase vaccination coverage among groups at increased risk of exposure given current outbreak data. Talk with your healthcare provider if you are unsure if you may be at risk for mpox.

Mpox Vaccine FAQ 

How is the vaccine given? 

​​JYNNEOS is given as two (2) doses at least four (4) weeks apart. If it has been more than 4 weeks since your first dose, get the second dose as soon as possible for the most protection. 

The vaccines are now typically given in the back of the upper arm. Previously, mpox vaccines were commonly given in the forearm. While it was also effective, some people had more skin reactions, including discoloration of the skin, at this injection site. 

Do I need a booster vaccine? 

Getting more than two vaccine doses (boosters or 3rd doses) is currently not recommended

How effective is the vaccine? 

  • ​The vaccine is very effective at preventing severe illness, hospitalization, and death from mpox (clade I or clade II). 
  • Studies show that two vaccine doses may also lower your risk of getting mpox up to 86-89%. 
  • It takes about 2 weeks from the second dose to have the most protection. 
  • ​​While uncommon, infections after vaccination are possible​. These infections usually have more mild symptoms. This is why it is recommended to consider other preventive steps​ and get tested if you have a new rash or sore—even if you were vaccinated. 

Can I get vaccinated after I was exposed? 

Yes, getting the vaccine right after an exposure is recommended if you have not already been vaccinated. It can provide some protection if given within 14 days after exposure to someone with mpox, before symptoms develop. The sooner it is given, the more effective it might be. 

Should I get vaccinated if I already had mpox? 

The vaccine is not recommended for people who currently have mpox infection or who had mpox infection before. Seek medical care if you have mpox symptoms. 

What about vaccination for clade I mpox? 

JYNNEOS is expected to be effective against both clade I and clade II mpox. CDPH continues to monitor the situation closely and makes recommendations based on available data. 

  • If you have only gotten one dose of mpox vaccine: Get your second dose as soon as possible for the most protection. 
  • If you have already gotten both doses of mpox vaccine: Boosters or third doses are not recommended​ at this time. 
  • If you previously had mpox infection (including clade II mpox): Mpox vaccine is not recommended at this time.​ Prior infection is likely protective from either clade of mpox per CDC.

Talk with your health care provider if you have questions about mpox vaccination.
