Role of Herd Immunity in COVID-19

Background: With the rise in cases of COVID-19, the concept of herd immunity came into play which is expected to play a very important role in the control of this pandemic. For herd immunity to work we require only a part of the entire population to be immune which can be either by vaccination or natural infection. Although we are exactly not sure about the lasting impact that these antibodies will have on us or about the re activation of virus, as of now this remains the best option with us to combat the disease process. The effectively of vaccine, virus transmission, and the level of pre-existing immunity along with other factors play a very important role in determining the time required to reach herd immunity. With this we can prevent the immune compromised or individuals with other co-morbid conditions predisposed to this disease as in them the disease process would be fast and response to treatment slow or undetermined. The main element of vaccine production depends on the population behaviours along with the pathogen. It is on the basis of these criteria that we analyse the study between herd immunity and COVID-19. As we know now that this disease spreads as the healthy individuals come in contact with infected individuals therefore the most effective way to prevent it is by maintaining social distancing. So with the herd immunity coming into play the transmission of the disease is stopped and we can achieve our aim of preventing the spread of the disease by making just a part of the population immune. Objective: The purpose is to review the article related to attainment of herd immunity in COVID-19. Methodology: For the review article we gathered the data from various data bases like PubMed, Google scholar, and science direct and other websites involving searches such as herd immunity, vaccines, natural immunity, COVID-19. Result: After reviewing the article we can say that herd immunity plays a very important role in controlling the transmission of COVID-19 Conclusion: After looking at all the perspectives although we conclude that herd immunity will play the leading role in the control of transmission but it is a very challenging task that would take a lot of time to become effective, till then measures such as social distancing, hygiene practices and sanitation should be considered to stop disease transmission.
