Covid-19: German city of Tübingen protects its elderly to avoid another lockdown

Can we prevent lockdowns by instead taking better care of at-risk and elderly people? Most governments have rejected the idea, but the south-western German city of Tübingen has made it a reality.

The strategy seems to be working: current infection rates in the city are much lower than during the first wave. Our correspondents report.
