On vaccine hesitancy and hesitancy to vaccinate

To understand the goal of a vaccination programme, one must understand the concept of herd immunity. Herd immunity occurs when a significant proportion of the population is no longer susceptible to infection. This protects the remaining susceptible individuals and stops further outbreaks. Practically, a herd can obtain immunity either by widespread natural infection or by vaccination. Some have touted the natural route to herd immunity. However, considering disease-related morbidity and mortality of SARSCoV2, this approach is not only costly but also not ethically sound. Vaccination remains as the great hope.
