What is the mpox vaccine?

The mpox vaccine (Imvamune®) protects against infection from the virus that causes mpox.  
It helps your body build immunity without getting very sick.
The vaccine can be given in two ways:
  • Before exposure to the mpox virus (the vaccine is given before getting exposed to the virus to help protect against mpox).
  • After exposure to the mpox virus, before you have symptoms (the vaccine is given after being exposed, ideally within 4 days, to prevent illness or severe outcomes). 
A supply of vaccine that protects against mpox has been made available to BC by the federal government. Vaccination has been offered to at-risk populations since June 2022.
People who are eligible can now book appointments for their first or second dose.
Eligibility for the vaccine in BC has been guided by information about people who have acquired this infection. Should the characteristics of these people change as transmission continues to occur, the eligibility may be adjusted accordingly. 

Who should get the vaccine?

If you are at increased risk of exposure to mpox or you have been identified by public health as being a close contact of someone with mpox, it may be recommended that you get the vaccine. You can find the eligibility criteria for the vaccine on the BCCDC's Mpox page
The vaccine is given in a series of two doses. You must wait at least 28 days after your first dose to get your second dose.
Due to limited supply, this vaccine is intended for residents of Canada or those visiting BC for prolonged periods of time. People from outside Canada should not travel to BC vaccine clinics for immunization; we cannot provide the vaccine to those visiting the province for the purpose of being vaccinated. Please contact your local Public Health unit for information about receiving mpox vaccine.

What are the benefits of the vaccine?

The vaccine can prevent mpox or make the illness less severe. This makes it less likely for you to pass mpox to others.

What are the side effects?

The vaccine is very safe. It is much safer to get the vaccine than to get mpox. The vaccine cannot give you mpox.
Common reactions to the vaccine may include soreness, redness, swelling, itching and a lump where the vaccine was given. These reactions are more common and last longer when the vaccine is given under the top layer of skin (intradermally) instead of into the fatty tissue just under the skin (subcutaneously). Skin may also become temporarily discolored when the vaccine is given intradermally. Other reactions include tiredness, headache, fever, chills, muscle or joint soreness, nausea and loss of appetite. Reactions to the vaccine are more common in people with atopic dermatitis (a type of eczema).
If you have concerns about any symptoms you develop after receiving the vaccine speak with your health care provider or call 8-1-1 for advice.
Always report serious or unexpected reactions to your health care provider.
