In the Netherlands, Protestants make up around 16 percent of the population. A small group of traditional Calvinists are opposed to vaccination and social distancing. Most of these believers, who live in a region known as the ‘Bible Belt’, were never vaccinated as children and are opposed to the idea of injecting sickness into a healthy body. Despite surging case numbers, they continue to attend Sunday services without face masks. But amid some of the country's highest Covid-19 infection rates, some of them are starting to shift their mindset.
