The development of vaccines that provide protection from SARS-CoV-2 infection is a global matter of life and death. An unrivalled effort is currently moving rapidly develop effective COVID-19 vaccines. Vaccines to prevent SARS-CoV-2 infection are considered the most promising approach for curbing the COVID-19 pandemic. Several COVID-19 vaccines are available globally COVID-19 vaccines have exemplify to bring forth a sufficient countervail response that protects against COVID-19. The site of vaccine delivery may impact the character of the immune response, Chest CT is a key for fast imaging tool inorder to diagnosis of COVID-19-infected patients especially in developing countries. In addition, chest CT can predict the disease severity by showing the percentage of lung involvement and hence give an idea about the prognosis of the disease. COVAXIN single dose vaccinated was 48 and with two doses was 48, and COVISHIELD single dose vaccinated was 130 and with two doses was 81 with 95% confidence interval (CI), 20% relative width of 95% CI, Severity of COVID 19 among vaccinated and non-vaccinated patients was compared. The severity of disease was less prevalent in double dose vaccinated patients when compared to single dosed, non-vaccinated patients.
