Putting too many eggs in the vaccination basket in order to prevent a local *transmission* has issues.
One is, what happens when, like the US, people stop getting vaccinated at the initial most enthusiastic initial rates?
cdc.gov/coronavirus/20…
What happens is massive exponential rise in cases and hospitalisations in that location because of too few/weak NPIs in place due to the earlier narratives which paraphrase as "we can live with it".
Another issue for interrupting transmission is it takes time to build up full immunity-even with shortened dosing intervals between doses. Yes, one dose makes a difference & is better than none. Get vaccinated if you can & if supply allows it & your GP has addressed your concerns
Another issue-we don't have good data on how well transmission is prevented by vaccination for Delta variant virus-definitely some. Seems to be quite a bit for other variants but if we don't know, we shouldn't speak with such confidence that vaccination will stop an outbreak
Perhaps the biggest single issue for Australia has been the AZ vs Pfizer issues and the supply issues.
Pfizer supply will soon pick up & AZ is safest for those >60y, with the suggestion you speak with your GP if you are under that age group & concerned about rare side-effects
By "rare" re: AZ I mean these figures from ATAGI's 30JUL2021 update...

What would I do? Okay. Keeping in mind I'm not in the room, not an Epi and I don't run this stuff. So a big pinch of salt.
But to answer this question for people angry at me for negatively pointing out that NSW is putting the rest of Australia at risk..
..because they started too slow (my key point, which doesn't help now, I know).
I'd reset.
I'd look at what the most stringent of the "Lockdown" rollouts from anywhere in NZ and Aus (planned or enacted) is, add anything more that can be added, ensure food and money can get to..
..those who will suffer most, and roll that out across all of NSW at once, all the same. And lots of different Comms. There is more that can be added if today's Penrith additions are a guide. So do that. Set a new benchmark. And this has to be done before any more of those..

Some international Tweeps seem to think *Australia* has lost its control over COVID-19. The map below shows Australian States and Territories. The yellow bit is where all the cases you're hearing about (100-200 per day) are from.
Hopefully, they'll regain control in coming weeks Image
The rest of Australia continues to manage cases at the border or is getting on top of some local community spread as usual.
Vaccination is ongoing but not at the rate many of us would like to see it. There are multiple reasons underlying that, principally issues with mRNA supply.
Our earliest "sovereign" vaccine had issues as it produced an HIV diagnostic cross-reaction. Our second most backed vaccine generated safety signals which - in the absence of community COVID-19 - created a risk imbalance due to TTS.

Impressively easy to get a test this morning at a Queensland Health testing facility. Found it online. No GP referral needed. Helpful people everywhere. All happened quickly and efficiently. Throat and both nostrils.
Waiting on that result with all those privileged expectations....
*Sampling facility 🙄

Yes, & if I *chose* to do these sports, I'd be *choosing* to take the risk.
I *chose* not to partake in any of those.
🎶One of these things is not like the other🎵
Until recently, those of my age couldn't make a *choice* even though there were options.
This a poor comparison
And admission: I don't have my own horse in this game because I was vaccinated with Pfizer in March as a frontline worker. I use my age (50 - still!!) as a example
This is a better comparison because I can't control getting homicided or car accidented.
However, I can *choose* not to stand in the rain during a lightning storm, and I'm a pretty good (& infrequent) swimmer.
But this is just about deaths? Why control the narrative that way?
