Comparative Study on Vaccine-Induced and Natural Immunity to COVID-19 in High-Risk Populations Dhanbad District
Dr. B. K. Pandey
Abstract: Background: The immune response following infection with a virus can be measured by detection of virus infected cells, IgM, IgG or total antibodies through immunoassay as well as by the detection of CD8+T cells. This prospective study investigates the comparative efficacy of vaccine-induced immunity and natural immunity in high-risk and susceptible groups in Dhanbad district. The study uses serological tests to measure immune response and assesses the benefits of 2 doses of Covaxine. The results provide insights into the need for booster doses and the overall immune response to COVID-19. Methodology: This study has been conducted in SNMMCH hospital to establish any improved immunity in high risk and susceptible groups of professionals (paramilitary forces involved to implement government protocols, individuals involved in health care facilities to ascertain any added benefits of 2 doses of Covaxine over natural immunity developed due to accidental infection through contacts before pre-vaccination period. TruNat and RT-PCR was done for isolating exposed groups. Another group formed for those who are potential candidates for immunization with 2 doses of Covaxine with previous history of exposure of Covid-19 virus. All healthy people who will healthy in all clinical parameters were included in study according to sop. Nasal swabs collected from all healthy individuals and CLIA method used to know the IgG cutt-off values. Aims & Objectives: This study aims to demonstrate any additional benefits for recipients of 2 doses of Covaxine, and to guide the potential need for precautionary or booster doses of the vaccine, especially for susceptible groups.
