Level of presumed adequate immunity towards mpox according to GBMSM’s numbers of independent risk factors for mpox diagnosis (unweighted dataa).

a
N = 2,460.
b
Due to the timing of the survey, we assumed that all GBMSM reporting mpox vaccination had only received one dose of vaccine.
c
All participants born before 1976 were presumed to have received smallpox vaccination.
