NZ got step 1 right (isolate) but massively dropped the ball on step 2 (vaccinate ASAP).
Australia meanwhile hasn't even vaccinated 5% of the pop as they put all their eggs into a political choice (on-shore produced AstraZeneca, support aussie produced!) and are now scrambling to find a replacement. There's not enough vaccine for demand.
Both took the same isolate approach, but it looks like NZ is gonna come out of this sooner.
I can guarantee you that this is not going to happen... I would be lucky if I am vaccinated this year... Vaccines are super scarce so we are real snails atm!
