Background: To curb SARS-CoV-2, various vaccines received Emergency Authorization Use by copious agencies. These vaccines are administered to health-care workers, front-line workers, elderly individuals and many others. Health care workers were the first to be administered with vaccines, thus, evaluating the antibody response helps to portray a picture of the burden of SARS-CoV-2 infection amid Health Care Workers.
Materials and Methods: The present study aimed to investigate the production of total antibodies against SARS-CoV-2 before and after vaccination (2 doses) among Health Care Workers along with associated factors. The present study was conducted on 60 healthcare workers as cases who got vaccinated for COVID-19. The semi-quantitative detection of anti-SARS-CoV-2 IgG Ab in the samples was detected using Erba Lisa COVID-19 total antibody indirect ELISA kit using standard protocol as described by the manufacturer.
Results: In the present study, co-morbidities such as hypertension was presented in only 8 (12.3%) individuals, diabetes in 4 (6.1%) and Coronary Artery Disease in 1 (1.5%). After first dose of administration, 86.67% HCWs were found seropositive for the anti-SARS-CoV-2 Ab while 13.33% were seronegative, however, after second dose 100% seroprevalence was observed amid HCWs. The statistical analysis depicted a significant difference (p<0>
Conclusion: The present study provides important information on the detectable levels of antibodies induced by COVISHIELD against the SARS-CoV-2 which was independent of gender and age.
