Booster or additional vaccine doses are not currently recommended for people who are already fully vaccinated (received 2 doses at least 28 days apart) or who have had mpox infection in the past.

Talk to your health care provider to see if vaccination is recommended for you.  Health officials do not currently recommend vaccination for members of the general public who are not at high risk of exposure to mpox.

Frequently asked questions

The mpox outbreak is ongoing with new types or clades of virus emerging. People who are vaccinated may have lower risk of severe disease or complications, but infection may still occur.

Please consider additional steps to reduce your risk of mpox, including decreasing the number of sex and intimate contact partners to protect yourself from mpox even if fully vaccinated.

CDC recommends that people get the vaccine within 4 days of being exposed for the best chance of preventing mpox. If vaccine is given within a couple weeks of exposure, it can still help reduce the severity of symptoms but may not prevent onset of disease.

Yes, if you received the first dose at a community event more than 28 days ago, you may receive a second dose at the Sexual health Clinic at Harborview or another private provider if vaccines are available.

Get the second dose of the two-dose vaccine at least four weeks after the first dose. Do not try to get a second dose early, as this may result in decreased effectiveness of the vaccine. You will start to build protection in the days and weeks after your first dose, but the vaccine won’t have its full effect until approximately two weeks after the second dose.

There is no maximum interval between doses so long as the second dose is given at least 28 days following the first dose. If there is an extended interval between doses, there is no need to restart or add doses to the series.
