Abstract

Covid-19 which is a SARS-CoV-2 (severe acute respiratory syndrome) has caused the new overall pandemic moreover is an arising virus profoundly contagious namely coronavirus. The unavailability of a particular antiviral treatment had led to the utmost destruction of life because of this virus. During this time, impressive efforts were placed into creating safe medications and immunizations against SARS-CoV-2. Just 56 vaccines made it at the different clinical stages from more than 80 clinical trials which had started including 23 antibody candidates got looked at moreover had affirmed for the use. Various types of variables are utilized for the production of such vaccines to start the immune reaction to produce antibodies in a person for killing the virus. The countries which are top of the race for producing vaccines are Russia, India, U.S.A., China as well U.K. Among the vaccines produced by these countries are Covaxin (India), Sputnik V (Russia), CoronaVac (China), AZD1222 (United Kingdom), BNT162b2 (Germany), and mRNA-1273(United States of America). We bring forth the certain potential factors that are required when creating vaccines as well as a comparative analysis of data obtained from SARS-CoV-2 vaccine trials for different vaccines as well as environmental impacts of its preparation.
