This is a big claim, right? I'm assuming optimal public health measures here is referring to Test/Trace/Isolate/Quarantine.

If so, it'd be pretty incredible if with 70% vaccination of adults, and no lockdowns, TTIQ holds up well enough to limit infections to 2.7K in 6 months.
I appreciate though that the Reff drops significantly when 70% of people are vaccinated, even though vaccines don't guarantee sterilising immunity.
For real though, if this happens - holy hell, that'd be amazing. I'm just wondering if 'optimal' TTIQ is what we'll see. Which is fine because the modelling gives scenarios for partially effective TTIQ as well
But this optimal scenario is a lot to accept on face value.

Great questions on #thedrum put to Prof Lewin. She confirms that once we are at 70-80% vaccination, whether we start off with 30 cases, or 100's of cases, we're in essentially the same situation. 'We're catching the same curve, just getting to the peak quicker', to paraphrase.
She's pretty clear on this. @bairdjulia asked the question a few times to confirm.
Re kids: Prof states modelling examined benefits of targeting different population w/vaccinations, and impact on transmission/hosp/deaths. 20-29, big pay off. 12-15's not as much. Affirms they SHOULD be vaccinated. But modelling says it shouldn't impact opening up plans.

Christian is one of the doctors who looks after people on ventilators 2 km away. This stuff triggers medicos in a way that a lot of people can’t understand.
I’ve told hundreds of people now that they’ve tested positive for Covid. I’ve had to decide when they were tipping over from being mildly unwell, to requiring oxygen in hospital. I’ve had to tell their family members that they’ve gone from being unwell to being critically ill.
Many time when I have these conversations, I witness people experience vulnerability, fear and uncertainty that is well founded.

Seeing maskless protesters spout lies that minimise the harms of this disease feels like a massive insult to the suffering I have witnessed.

Holy fuck. If Vic waited, it would have been game over.
We must hold it together for 3 months. If, I stress, if, we get the outbreaks around Aus under control, we can't risk another. That's playing russian roulette with 5 full chambers. Bolster quarantine chain. Strategically vaccinate, including contacts of quarantine workers
Currently household members of quarantine workers are eligible - not enough. we must reach out to them, incentivise it. Include their social contacts too. Pay them a grand each. Who the fuck cares? Do you know how much we've spent on submarines that don't submarine very well?

If NSW is the only place with numerous unidentified chains of transmission, surely its in the interest of all states to divert majority of vaccines to NSW to end this outbreak? 1-2 mil doses of Pfizer in next month of lockdown could radically change transmission dynamics.
Vic is getting this outbreak under control- what’s the biggest risk after its sorted and lockdowns end? Probably the reservoir of 100s of covid cases across the border. Same for QLD. Same for any state that literally doesn’t have Resident Evil style laser beams at the borders.
There probably is a mathematically optimal point to that balances the benefits of vaccinating nsw to control outbreak vs the benefits to other states from vaccinating their own populations to protect against leaks. point is - the 2 SHOULD be balanced, wherever the sweet spot is.

Lockdown with couple of cases- this is delta life. It’s obvious now- tracing alone can’t RELIABLY control outbreaks. If we somehow avoid permanent seeding of Covid, there’s one way to avoid future lockdowns.

Bolster the shit out of quarantine chain till Aus is highly vaccinated.
Mandate, enforce, audit airborne precautions and vaccination for workers.
Incentivise contacts of quarantine chain workers to get vaccinated with Pfizer. Their families. Their mates.
Big difference between making people eligible, vs actually reaching out and getting it done.
The travel cap has been cut in half and that may help. In the meantime ventilation should be audited regularly with air purifiers to be used widely.
spending a few hundred million means nothing when we are trying to save many lives and billions of dollars per week.

So a few weeks ago, I met someone (not a patient) who said 'Hmm I don't think I'll get the vaccine, I heard it may cause infertility' - (a comprehensively debunked piece of misinformation).

Well, yesterday I overheard him saying something that made me laugh with joy.
That first time we spoke, I asked him where he'd heard this claim of infertility (he couldn't remember). I told him I'd heard something similar too, and looked into it. I told him where the claim originated, and why I didn't believe it. He went 'huh'.
I didn't know for sure if he was persuaded by this. In a way I was too late - two other people I know were now also repeating this false claim. Where did they hear it from? From him. Misinformation was miles in front of truth.
But I also had time - I knew I'd see him frequently.
