Matthew Turner et al. Emerg Infect Dis. 2022 Nov.

Abstract

We report a case of monkeypox in the United States in a patient who had been vaccinated with ACAM2000 smallpox vaccine 8 years earlier. Despite his vaccination status, he still contracted disease. He showed prodromal symptoms preceding development of painless penile lesions that later coalesced.

Keywords: ACAM200 smallpox vaccine; United States; acute infection; immunization; men who have sex with men; monkeypox; monkeypox virus; sexually transmitted infections; vaccination; vaccine-preventable diseases; vaccines; viruses.
