And of course MLM has already weighed in:
From BAC:
Moving towards an eight-week gap between AZ doses 'a good idea': Professor McLaws
"The idea of moving a second dose forward will be a good idea, but we may have to have a booster shot after that. Because if we start moving away from that 12 weeks, your antibody response may not be as good as it could be.
"But given that we are in dire straits at the moment with Delta, we do not want it to go across any state borders, we do not want it to go to the elderly, it is a good idea."
"The first dose of AstraZeneca, against Delta, we are only protected at about 33 per cent compared to what you were protected previously. That is the same with Pfizer.
"Once you get a second dose, your protection goes up to about 60 per cent, which is not as good as it was before Delta started circulating, but still, it is very good. It is better than nothing, and it is better than 33 per cent.
"So please go get a second dose, as the Prime Minister suggested, it is a great idea. Later on, the states will tell you when you need to have that third booster, because we will all need to get that third booster."
Of course we aren't actually in dire straights, health systems are coping and cases numbers arent rapidly growing (like last winter), they are relatively steady
