Which statement correctly describes smallpox vaccination use during the monkeypox outbreak?

• A. The Vaccine Was Used Only For Pre-Exposure
• B. The Vaccine Was Used For Pre- and Post-Exposure
• C. The Vaccine Was Not Used
• D. The Vaccine Was Completely Ineffective

Answer: (B)

Cross-protection among orthopoxviruses means a smallpox vaccine can reduce the risk of monkeypox. During the monkeypox outbreak, vaccination was used both before exposure (pre-exposure prophylaxis) for people at high risk—like healthcare workers and outbreak responders—and after exposure (post-exposure prophylaxis) for contacts of a confirmed case to prevent disease or lessen its severity. The strategy of vaccinating contacts quickly after exposure helps interrupt transmission, while pre-exposure vaccination protects those likely to be exposed in the course of their work or duties. Because the vaccine was used in both contexts, the statement that it served for pre- and post-exposure is correct.
