Antibody responses in omicron BF.7-infected patients vaccinated with inactivated SARS-CoV-2.

Objective: Our study aimed to investigate antibody responses in omicron BF.7-infected patients after being vaccinated with inactivated SARS-CoV-2.

Methods: Blood serum samples were collected every 2-7 d, 1 w before infection, during the acute infection period and recovery period, and every month after recovery to detect IgG, IgM, IgA, neutralizing antibodies, and neutralizing antibodies against different omicrons in the acute phase.
