Be alert for breakthrough mpox in fully vaxxed patients, say doctors
Case reports suggest breakthrough and repeat infections happen but are generally less severe.
A spate of breakthrough mpox infections in fully vaccinated patients suggests that vaccine-induced immunity does not offer complete protection against infection, doctors warn.
Repeat infections have also occurred, pointing to waning natural immunity against the mpox virus, say authors of two separate case series covering 39 men who have sex with men (MSM).
