ABSTRACT
India has experienced two severe waves of infection with COVID-19. Since there isn't any effective drug, emerging variants of the virus, an unknown epidemiological life cycle, lockdown and restrictions at public places slowed the spread of novel corona virus in the country. However, a large number of new COVID-19 cases and deaths have been reported from across the country. We carried out a study to evaluate the effectiveness of vaccination in India, randomly selected five states and a union territory to control the severity of COVID-19 (case fatality rate). During the study period, March 21st 2020 to 6th August 2021, with the initiation of vaccination, the case fatality rate was reduced to less than 1.0% in the selected states and union territory. Thus, vaccination for COVID-19 infection is found to be effective in decreasing the severity of the disease. The eligible population should get themselves inoculated at the nearest health facilities. © The Electrochemical Society
