sorry if my flippancy offended you.It's not "whatever" and it's not "some political urgings", it's literally the ATAGI advice.
ATAGI continues to recommend a shorter interval of 4 to 8 weeks between the first and second doses of COVID-19 Vaccine AstraZeneca in an outbreak (versus the routine 12-week interval that provides optimal longer-term protection) so that maximal protection against COVID-19 can be achieved earlier.

Maybe I should have said "information in the media" but for me it was usually what a politician was saying as I never bothered going to the Atagi website.
Either way, if we had known efficacy was only 55% at 9 weeks (ie beyond the 8 weeks = whatever) we would not have bothered presenting at the vax centre. Makes you wonder though just how effective the vaccine is at 4 weeks, and whether changing the advice was derived from the best outcome for an individual or to transition a population for epidemiological purposes.

And many other "off topic" issues?Is it possible for this thread not to continue descending into detailed vaccination discussion?
And many other "off topic" issues?
This thread is similar to a virus: it grows exponentially and is becoming unhelpful.
Federal CHO Paul Kelly just said the covid zero strategy is dead.
Also implied the Doherty modelling supports the NSW strategy, regardless of the starting point it was always about exponential growth and protecting people from hospitalisation and death. But will be updated.
Emphasised that WA agreed to the plan several weeks ago.
At one point a man arrived on horseback and charged down the street shouting: “Cross the border. Everyone cross the border, they can’t hold all of us.”

The problem was that the Doherty Institute was asked the wrong question. They modelled what they were asked which was for an outbreak commencing from a Covid Zero starting point, and then to 30 cases and then on.
What we really need to know is what vaccination rate is required for a steady state (in terms of health outcomes) ongoing endemic from Covid19, including any transition phase to get to that steady state.
The Doherty Institute is quite capable of modelling this, and so it will be interesting to see what they are asked to model this time. Presumably these will be a range of scenarios starting with different levels of community spread, rather than virtually no cases.
The other flaw is that it only looked at an 180 day period. As covid looks to be endemic, we are heading towards a living with covid situation, and so we really need a longterm living with covid framework and not just a 180 horizon.
180 days for example is not useful for planning longterm health resources. How many ICU beds to we need on an ongoing basis,. how many outpatient clinics for longterm covid etc.
It will most likely be somewhere around 80%-ish of fully vaccinated adults still in terms of not many interventions.. However the real word of our own hospitals will be ultimate indicator.
Including the effects from vaccinated children would also be interesting to see. so vaccinating children may not be until 2022.
I agree, this is where I get stuck on the modelling discussion. The difference between a zero starting point and a 1,000 starting point must be what, a few weeks or a month at most, with a relatively open economy?But as Paul Kelly said, the starting point is inconsequential when you’re dealing with exponential growth. He has faith in the current modelling (as do I for what it’s worth)
we are getting the second at 12 weeks.The data is unclear. Studies are now showing AZ has a longer lasting efficacy than Pfizer.
The phrase “don’t let the perfect be the enemy of the good” applies here. Follow the health advice, get both jabs.
Exactly. Allowing also for additional immunity due to natural infections.The difference between a zero starting point and a 1,000 starting point must be what, a few weeks or a month at most, with a relatively open economy?

I have faith in the modelling. I just think that what they are modelling is not correct.
The growth will not stay as exponential growth. It simply cannot. It will become more a steady state condition of the virus always being there, and moreso once we genuinely open up to free international travel again. No doubt it will fluctuate somewhat, though so far would seem that it will not be as seasonal as the flu is. so they need to model long enough to see when that steady state is likely to occur.
Just on the modelling:
It is not just the computer modelling that you use. It is what inputs you put in, and what you are trying to model.
They only looked at 180 days, and a covid zero starting point..
My view is that they need to model over a longer duration, and also with different numbers of community spread when you start.
Plus also what say might happen with higher vaccination rates. Say 80% of adults and say 50% of children.
In other words, may as well just keep watching what happens rather than fretting about the government's models.
You should apply to be the federal CHO. You clearly know more than him.
Polls and models are sometimes commissioned to get the answer that someone wants.
