Abstract

Obesity may downregulate vaccine-induced immunogenicity, but the epidemiological evidence for the COVID-19 vaccine is limited, and the sex-associated difference is unknown. It was observed that a higher body mass index was associated with lower titers of spike IgG antibodies against SARS-CoV-2 in men but not in women.
