Abstract

The vulnerability of an innumerable number of people worldover to COVID-19 is still obvious though it has been well over an year since the virus first emerged. The humanity has faced second wave of infection by SARS-CoV-2, and it has been a way of life by now to change our life styles, particularly adopting work from home, or simply staying back at home for the students pursuing studies at Colleges and Universities or the minors at primary institutions. These methods have been adopted to break the chain of virus that could reduce the opportunities for the virus to spread. Vaccines leave an imprint on our bodies to enable them to fight the infection and are “the” exit strategy from the pandemic. The current paper reviews various types of vaccines and the recent advancements made to fasttrack preparations of a wide variety of newer vaccines that could be economical or may take the form of a capsule or similar other variant.
