Abstract

•JYNNEOS vaccination produces robust anti-orthopoxvirus antibody response.•Naive vaccinees generate OPXV-specific IgM early after vaccination.•IgG responses peak around 2 weeks after second vaccine dose.•Titers wane at 2 years, and more rapidly in naïve vaccinees.•Antibodies neutralize VACV and MPXV differently, but had similar rise from baseline.
