SARS-CoV-2 Seroprevalence Among Whole Blood Donors During First Wave of Covid-19 Pandemic in India

This study also analysed the mean neutralizing capacity of SARS-CoV-2 antibodies among 97 blood donors which was 71.9 (SD:  + 21.03, range 15.5 to 97.3). Donor samples with SARS-CoV-2 IgG S/Co >  9.5 had significantly higher neutralising capacity (>  68%) when compared with donor samples of S/Co <  9.5 (p value 0.000). Real-time seroprevalence studies will help to know the herd immunityamong the blood donors which will assist in knowing the Covid-19 transmission dynamics, distribution of immunity levels at a particular point in time, immunity gaps, development of novel therapeutics and prioritize the vaccination programmes to high risk individuals.
