The basic reproduction number and herd immunity for COVID-19 in India

Objectives: To estimate the basic reproduction number and herd immunity in India relative to the viral disease COVID-19. Methods: In this study, we analyzed literature from March-2020 to January-2021, which were related to the basic reproduction number and herd immunity of COVID-19 in India. Also, we found the mean value of the basic reproduction number and herd immunity as a result. Findings: According to our study, the basic reproduction number and the percentage of the herd immunity ranged from 1.2561 to 3 and from 20% to 66%, respectively. The mean value of the basic reproduction number and the percentage of the herd immunity is 2.0546 and 51% respectively. Novelty: To the best of our knowledge, no such studies have been conducted in India. Keywords: Basic reproduction number; Herd immunity; COVID19; Vaccination; Regression; etc
