Monkeypox vaccine – King County

When should I get the second dose?

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 wont have its full effect until approximately two weeks after the second dose.

This is an emerging outbreak, so we dont yet know how much protection the vaccine can give. Please consider other recommendations, including decreasing the number of sex and intimate contact partners to protect yourself from monkeypox even if fully vaccinated.

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.
