“Vaccine hesitancy” is referred to as delay in taking vaccine or refusing to take vaccine. During the initial Covid wave, “vaccine hesitancy” —could prove deleterious for the US’ COVID-19 mitigation efforts, making herd immunity difficult to achieve. Researchers have identified various variables such as demographic, political, psychological, and health-based variables associated with vaccine hesitancy that could be used to identify potential hesitancy score of a person. Researchers collected data from 3353 US adults to create a predictive model of COVID-19 vaccine hesitancy.
