A prospective study of IgG antibody concentrations among 201 individuals in India who tested positive for SARS-CoV-2 found that only 28.4% of participants retained IgG antibody responses at 45-65 days follow-up. The authors highlight the need for future studies that use quantitative antibody assays and measure neutralizing antibody to assess risk of reinfection.
