Antibody Responses after a Single Dose of SARS-CoV-2 mRNA Vaccine

Antibody Responses after a Single Dose of SARS-CoV-2 Vaccine Reported results of immunization with SARS-CoV-2 vaccine have focused on two doses given to seronegative persons. In a small study involving health care workers, antibody responses were examined after a single dose of vaccine. Consistent increases in antibodies to spike protein subunits S1 and S2 and the receptor-binding domain were noted.

Automated summary
