Expert opinion based on in vitro studies of neutralising antibody levels should be properly debated in academic circles, but by itself is not helpful for policymakers. Hong Kong, with its quite high vaccination rate of about 80 per cent for the first dose, should aim at ‘flattening the curve’ of an Omicron wave, rather than preventing it.

Switching to a ‘live with it’ policy relies on vaccines alone doing the job, when new research suggests declining efficacies as new strains emerge. Hong Kong should wait and see.
