Ok, I hear NSW wants to relax things at 50% vaccinated. In a previous timely post I though it would be 70%, because in the UK's case, that was borderline compromise. But I was wrong. I also suggest the magic number for Delta is north of 80%. Lots of chatter on modelling provided by the Doherty Institute would be complemented with ongoing assessment of.... (politicians can make stuff up..).
Here is what you need to know: The model must be made public and disclosed. I do not know the risk ratings. But someone does. And other models listed. Then things are complicated by regional variations, vaccination homogeneity, infection reservoirs and control/escape vectors. My words, maybe not of those who model. There is also a lead time to vaccinate, and the outbreaks have gone viral in same places that recorded high vaccine 'wastage' rates when the blitz medicos did the rounds to remote areas. I note they seem to follow interstate major roads.
There is no wartime footing. If that was the case then the citizens/SES would be called to block off roads, and forward plates/details to the police. If we are not to have mandatory vaccination, then people who find themselves in trouble, must accept personal responsibility for their own actions and community deaths (excluding genuine medical reason persons).
Looking at the numbers and spread, and the tragic expansion to the upper west inland, where 9% or less vaccination ticks most of the factors listed above. The un-averaged risk multiplier in these spots is through the roof. Add diabetes+obesity = perfect storm.
Do not tell whoppers. NSW will be locked down >4 weeks. NSW has lost it. And this 50% number will not work. Every LGA needs to get over 50%, or those undervaccinated areas will reignite fresh outbreaks. Time to break out the SES, 4WD clubs, and the shooters, for some enforcement spotting- if they are vaccinated.
