Persistence of the neutralizing antibody response after SARS-CoV-2 infection.

ABSTRACT:

Objective

Neutralizing antibodies are among the factors used to measure an individual's immune status for the control of infectious diseases. We aimed to confirm the persistence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) neutralizing antibody levels in patients who had recovered from coronavirus disease 2019 (COVID-19).

Methods

Plasma donors in South Korea who had completely recovered from SARS-CoV-2 infection had follow-up testing to determine the persistence of neutralizing antibodies using a plaque-reduction neutralization test and ELISA.

Results

Of the 111 participants-aged 20-29 years, 37/111 (33.3%); 30-39 years, 17/111 (15.3%); 40-49 years, 23/111 (20.7%); 50-59 years, 21/111 (18.9%); 60-65 years, 13/111 (11.7%); male, 43/111 (38.7%); femal
