    Sweden is playing Russian roulette. No one knows of how durable the assumed immunity might be, or if the immunity is possible to achieve in general. If this new coronavirus behaves similarly as its relative SARS-Cov (2002-03), the immunity might remain for 1-2 years. But it's also very likely that this new coronavirus mutates and some people might have a short period immunity against strain A or B or C or D etc. The only way to get herd immunity is to develop a working vaccine and still we'd have several uncertainties. But this Swedish strategy is very expensive, at least if measured with a number of corona victims.
