Spirituality and religiosity contribute to ongoing COVID-19 vaccination rates: Comparing 195 regions around the world

Vaccine hesitancy has taken global prominence with the rapid spread of COVID-19, but what factors are related to this considerable variation in vaccination rates globally? Three studies that encompass 195 unique regions from around the world found that the relative spirituality and religiosity of a region predict ongoing COVID-19 vaccination rates, such that those regions higher in spirituality and/or religiosity are regions with lower COVID-19 vaccination rates. In Study 1, data from 23 regions globally were obtained, and both spirituality and religiosity were negatively associated with vaccination rates. These effects held when applying two methods to account for vaccine supply issues. In Study 2, data from 144 regions globally were obtained, and once again religiosity negatively predicted COVID-19 vaccination rates. It remained a significant predictor of vaccination rates when controlling for GDP, population age, collectivism, general skepticism towards vaccinations, and previous inoculation history. In Study 3, data from all USA states and the District of Columbia were obtained, and religiosity and spirituality once again were negatively associated with COVID-19 vaccination rates. Effects held controlling for other factors. Across studies, spirituality and religiosity account for a large amount of the variance in vaccination rates. These results suggest that real-world behavior can be predicted by the relative spirituality and religiosity of a region.
