This review gives an overview on the correlation of herd immunity with the propagation of the covid disease and the underlying mechanism of the same. A literature review of all the relevant papers related to the topic was conducted from articles ranging from 2000 to 2020. The outbreak of the novel coronavirus, COVID-19, has been declared as a global pandemic by the WHO. Various models, such as the SIR model, epidemiological model, social distancing model, contribute in determining the impact of herd immunity in the propagation of disease, which could be symptomatic or asymptomatic. Herd immunity can be measured by testing a sample of the population for the presence of the chosen immune parameter. These herd immunity effects have also been incorporated to create economical vaccination programmes. This article brings forth the fact that usually, herd immunity does not develop in a year or two. For herd immunity to come into play, an effective, safe vaccine is a must. If we have a vaccine, we may be able to develop herd immunity against the virus in future provided the majority of the population are vaccinated. Overall, this correlation is vital because it provides evidence for the earliest planning of vaccines and helps in the initiation of the herd population and helps protect vulnerable individuals in the community who have low-functioning immune systems.
