Herd immunity in a coronavirus disease 2019 epidemic model with consideration of vaccination and quarantine interventions
Abstract
During the pandemic of COVID-19, people had reduced contact among each other. As a result of this behavior, several factors, such as economic conditions and the teaching and learning process, have been affected. Hence, it is important to identify whether the impact of COVID-19 is no longer as severe as when it was first observed. The study aimed to analyze herd immunity against COVID-19 in Indonesia according to the bifurcations and simulations of mathematical models of COVID-19 transmission. Based on the bifurcation of the disease system, whether the current pandemic was controlled with standard interventions was evaluated. The system behavior can be compared with herd immunity that should be achieved in a specific population. Thus, whether a system has resulted in the achievement of herd immunity can be evaluated. The behavior of this system can provide information on the achievement of group immunity during disease outbreaks.
