Scott3:
We absolute should be doing everything we reasonably can to minimise risk of an outbreak here for the next 8 - 10 weeks that gives us 4 weeks to ramp our vaccination program up to say 300,000 doses a week, and 4 - 6 weeks running at that rate. Should be up around the 3m doses given point then (a little over 30% of the population with first doses, a little under fully vaccinated). That level of vaccination should be starting to drag down the R0 a little and make the virus easier to eliminate if it gets into NZ.
This is absolutely true - we need to desperately step up our defence above "level one".
CT of Delta presents a considerable additional challenge. This from ABC News:
Sydney's lockdown will need to last until September to suppress case numbers, new modelling shows.
The model was developed by the Populations Intervention Unit at the University of Melbourne, and bases the lockdown ending when the median number of new daily COVID-19 cases falls below five.
It shows that, on the current Stage 4 Sydney lockdown settings, that threshold would be reached on September 4.
The model was run 10,000 times to take uncertainties into account.
It might be better, it might be worse, but it's not like locking down CT outbreaks of early C-19 variants.
