Residual Immunity from Smallpox Vaccination and Possible Protection from Mpox, China

Emerg Infect Dis. 2024 Feb;30(2):321-324. doi: 10.3201/eid3002.230542.ABSTRACTAmong persons born in China before 1980 and tested for vaccinia virus Tiantan strain (VVT), 28.7% (137/478) had neutralizing antibodies, 71.4% (25/35) had memory B-cell responses, and 65.7% (23/35) had memory T-cell responses to VVT. Because of cross-immunity between the viruses, these findings can help guide mpox vaccination strategies in China.PMID:38270156 | PMC:PMC10826747 | DOI:10.3201/eid3002.230542
