Sweden has not banned public gatherings like most countries have because of the coronavirus pandemic. Crowds recently gathered near the waterfront in Stockholm to enjoy the sun. Anders Tegnell said he is not worried. He is the country’s medical official leading the fight against the coronavirus pandemic. The 63-year-old has become famous in Sweden. He appears on television every day. He tries to calmly explain the development of the outbreak. Countries across Europe have restricted the movement of their citizens, but Sweden has not. Tegnell says Sweden is finding a different way that is more sustainable. Sweden is using what some call herd immunity. This can involve letting people become infected so that large numbers of people develop immunity in the population.
