Across Europe, Covid only kills the under 60's in very small numbers. For example in Italy which has had a relatively high number of deaths overall, less than 3% were under 60 years old. In England and Wales the corresponding percentage is around 7%. This difference shows up in the Euromomo charts, where the UK is more or less unique in having high mortality in the under 65's.
The question remains: Are our unprecedented quarantines and lockdowns a proportionate response to the disease?
