Somebody mentioned paying senior citizens to get vaccinated. Did this in Makati, metro Manila, and achieved a 105% vaccination rate of the oldies. Only about HKD160 each.
They really don't want to have to face the “everyone is vaccinated, what next?” question a moment sooner than they have to. So this will keep getting dragged out.
Fly back seven days early, with stopover in e.g. South Africa - get the first 7 days quarantine free at Penny's Bay, no need to rebook/extend your 14 day hotel quarantine!!!
