A study on seroconversion following first & second doses of ChAdOx1 nCoV-19 vaccine in Central Kerala.

Background & Objectives: Vaccination against COVID-19 induces spike protein-binding IgG antibodies, a robust correlate of protection against COVID-19. This study was undertaken to assess the humoral response after completion of both the doses of ChAdOx1 nCoV vaccine in healthcare workers (HCWs) at a tertiary care health centre in India.

Methods: A cross-sectional COVID-19 vaccine-induced antibody study was conducted among HCWs.
