Forty-nine individuals with paired samples at 2 and 24 weeks post second dose of Sputnik V were analyzed for Anti-S/RBD and neutralizing antibodies. Cohort was differentiated into individuals (i) Non-COVID (n= 31); (ii) COVID-PreV (n = 9); and (iii) COVID-PostV (n = 9). Anti-S/RBD IgG tested with COVIDAR (IP), Anti-S IgG tested with Roche (U/mL), and neutralizing titers (NT) against ancestral SARS-CoV-2, Gamma and Delta, are shown. Samples with NT below 8 were set at 1. ND, not determined.
