Reach of Mpox Vaccination One Year After the Start of the Epidemic: Results of a Community-Based Survey of Men Who Have Sex with Men, San Francisco, USA.

Our survey of venue-attending men who have sex with men (MSM) in San Francisco (N=545) found that one year after the first reported case of mpox, 76% (95% CI 72-79%) self-reported receiving at least one vaccine dose and 58% (95% confidence interval [CI] 54-62%) received two doses. Vaccination was higher among MSM born outside the US (adjusted odds ratio [aOR] 1.95, 95% confidence interval [CI] 1.12-3.39), with some college or higher education (aOR 1.90, 95% CI 1.10-3.28), and seeing a healthcare provider in the last year (aOR 2.75, 95% CI 1.56-4.85). No differences in vaccination were found by race/ethnicity, age, and HIV status. Findings show rapid mpox vaccination uptake among MSM in San Francisco, although lagging behind among US-born MSM and those with lower education.
