The Victorian outbreak started via a superspreader event in NSW, where the householders failed to advise tracers for two days after the outbreak was discovered that the grandfather had attended (quite legally) from Melbourne and returned home.
Sydney's outbreak continues to decline, but remains stubbornly over 150 new cases a day. For most of the last week, over half of new cases have been from outside Sydney, even though only around 20% of the state population is outside Sydney.
We are waiting, and waiting and waiting...... for our current vaccination effort to replicate the effects that high vaccination rates have had in progress of the outbreak firstly in Sydney, and now less convincingly in Melbourne.
In Auckland where the vast majority of the cases are current vaccination rates for 12+ are 92% 1st dose 83% 2nd dose which by my reckoning is about the same level as when things peaked in Sydney, and ahead of when Melbourne peaked.
The better Sydney result may be down to better targeting of the vaccination program there, concentrating on the most vulnerable area first, where here vulnerable South Auckland has only just broken 90% first dose, whereas the more affluent Central area has surpassed 95% first dosed.and 87% second.
