Pre-existing antibody levels negatively correlate with antibody titers after a single dose of BBV152 vaccination
Abstract
Serosurveillance studies show a heterogenous mix of the Indian population with immunity to COVID-19 due to vaccination or natural infection. Here, the authors enrol subjects representative of the general population, to assess whether pre-existing antibodies are further boosted by a single dose of an inactivated SARS-CoV-2 vaccines, BBV152.
