Hong Kong’s Covid contact-tracing app has begun flagging users who haven’t uploaded vaccination records, as the city struggles to contain a resurgent outbreak that’s taxing its health system.

The LeaveHomeSafe app – mandatory for entrance to many restaurants and other public venues – was updated over the weekend and now flashes a red QR code on its check-in page for users that haven’t linked to an official immunisation record.
