History of Early Invention of Covid-19 Vaccines which Saved Mankind from Deadly Global Pandemic

The goal of the study was to discuss and analyze different Corona virus vaccines based on how they compare to other viruses in terms of their antigen S proteins. A vaccination is a sort of medication used to strengthen the immune system's defenses against infectious organisms including viruses and bacteria. The World Health Organization describes them as "one of the most effective ways to prevent diseases." The human body has an innate defensive mechanism against harmful pathogens like bacteria and viruses, making it exceptionally resistant to illness. Covid-19 pandemic shocked and locked whole world in year 2019 and 2020. Maximum death occurred in USA followed by Italy and Spain. Collecting data of Covid 19 vaccination preparation from internet and other all social network sources and afterwards discussing them. The data discussed here cover the Covid 19 vaccine pre invention. According to available information, in Germany and UK, the vaccine developed from chimpanzee’s Corona virus is ahead of every other type as now they got permission of even testing on human volunteers. Even though the entire scientific community is working to develop a vaccine and treatment for COVID 19 on an urgent basis, a fully functional, effective specific vaccine won't be accessible to the general public for about a year. Until then, social isolation and lockdown are the only methods that can stop the disease's spread, morbidity, and mortality across the entire planet.
