The mpox (monkeypox) vaccine JYNNEOS is currently available in NSW for people who are considered higher risk of getting mpox. Find out what to expect, possible symptoms and how to care for your injection site.
Mpox is a viral infection that causes a rash and is usually spread by skin-to-skin contact with someone who has mpox. Most people recover within a few weeks, however severe illness can occur, particularly in immunocompromised people.
The mpox vaccine JYNNEOS is currently available in NSW for people who are considered higher risk of getting mpox. Information from clinical trials shows the vaccine is effective in preventing mpox.
To be fully vaccinated you will need to receive two doses of the vaccine at least 28 days apart.
It will take two weeks after your second vaccine to provide the best protection against mpox. Vaccine does not provide full protection against mpox, especially if you have received only one dose. Once you have been vaccinated, you should continue to protect yourself from mpox infection by avoiding direct skin-to-skin contact, including sex or other intimate contact, as well as items such as bedding or towels with a person who has mpox.
The JYNNEOS vaccine does not transmit mpox or any other pox virus to other people.
As with any vaccine, you may have some side effects after receiving this vaccine. Most side effects are mild, do not last long and happen in the few days after getting the vaccine.
Common side effects reported in clinical studies after receiving the vaccine include:
People with atopic dermatitis (eczema) may be more likely to have side effects after vaccination compared to those without this condition.
You should seek medical attention after vaccination if you:
Vaccination is only one way to prevent mpox infection.
As there is still a risk of infection following vaccination, it’s still important to take steps to reduce the chance of catching or spreading mpox.
If you start to experience symptoms:
The mpox vaccine can be given to reduce severity of the virus if you have been exposed to a person who has it. Ideally vaccination should occur within four days of exposure but may be given up to 14 days in vulnerable people. Your local Public Health Unit (1300 066 055) will be able to advise further.
The vaccine will be given by trained staff under the skin (subcutaneously).
It is important to get your second dose of the vaccine for maximum protection.
Until you receive your second dose, and even after being vaccinated, continue to look out for mpox symptoms and self-isolate if you experience any symptoms, and avoid sex and other close physical contact with people who have symptoms to reduce your risk of exposure.
