Herd Immunity: An end to the global covid 19 pandemic crises
Abstract
A good deal of scientific and clinical information has been collected in the wake of Coronavirus disease (COVID-19). The virulence, infectious nature, and molecular diagnosis of the virus need to be studied more in order to obtain more information because the SARS-CoV-2 is undergoing a genetically normal evolution, which is a dynamic process. The immune system engages in the fight against viral infection through pathogen elimination, cellular homeostasis, tissue repair, and memory cell generation. Which are reactivated upon exposure to the same virus and preparing the body for future encounters with the virus through vaccination. As a result of vaccination or developing immunity from prior infection, a population obtains indirect protection against infectious disease. When this immune response occurs in 80% of a population, it is known as "herd immunity". SARS-CoV-2 has spread rapidly across communities. If it is to be stopped, a significant percentage of the population must be immune.
