"recommended interval for the 3rd dose is 2 to 6 months after the 2nd dose of vaccine. o A minimum interval of 4 weeks may be considered in exceptional circumstances...." ATAGI Vers 1.0. 7 Oct. Inline with Israeli evidence.

Kid vaccines prevent illness, spread & prevents rare complications - brain inflammation due to mumps 1 in 200 & 1 in 1000 due to measles; 1 death/year from rotavirus. Approx 20,000 kids 0-9 & 22,000 10-19yr had Delta in Vic & NSW. That's enough reason to COVID vacc 5-11 yr.

Like Israel (in 60s% coverage), SG opened up too soon (in 70s%).

First indicator of Vic peaking came yesterday. Same trend today & death rate lower than NSW. Well done Vic. Keep safe, stick to the rules & get vaccinated. Getting vaccinated lowers circulating virus which lowers cases and lowers death rates.

Rapid antigen tests are ideal for screening and allowing us to open up more safely
DIY #COVID19 tests that give speedy results are helping the rest of the world resume normal life. Tonight, a million new kits have landed in Sydney, and authorities are under pressure to allow their widespread use. @gracefitz_9 #9News

Congratulations, this is a safe way to open up. Rapid antigen tests (RATs) have been available to us for months. Should be used to screen & safeguard our boundaries/borders, venues, schools & institutions. Best RATs match PCR, take 10-15mins & cheaper. abc.net.au/news/2021-09-03/w…

The maths will show as total numbers increases in unvaccinated young so will the number hospitalised. If the young remain highest group unvaccinated then hospitalisation will mostly be young. In UK 5-24yo are highest Delta numbers & Delta increases hospitalisation by two fold.

"Can't live in lockdown forever" BUT DON'T SACRIFICE OUR YOUNG. Restrictions mustn't lift until young have vaccine access equity; they carry highest caseload yet lowest vaccination. Without vaccination, young will have highest caseload & therefore highest numbers in hospital.

Great to see more Pfizer. Great to see 20-39 yo targeted. Great to see some action on rapid antigen testing. Hopefully better late than never. Evaluating obvious epidemiological patterns for obvious rapid outbreak management does not require waiting for theoretical modelling.

3/3 NZ is targeting 78% of total population and Singapore is targeting 75% of total population. National Cabinet modelling must to be published for public review & for Australians to understand why Government targets are so low compared to estimated local and overseas targets.

2/3 I calculated we need 68%min & preferably 80% of total pop to be vaccinated. Grattan Institute recommends "fully vaccinating 80% of all Australians, & 95% of the over-70s", to "give us the best chance of gradually returning to normal life – with open borders & no lockdowns".

1/3 National Cabinet targets of 70% & 80% (16 years +) vaccination thresholds equate to 56% and 64% of total population vaccinated. Australia must do better than these vaccination rates because.....

RATs (rapid antigen tests) performed daily identifies someone infected early before they show symptoms. Early detection means they are isolated faster and their memory is fresh when questioned during contact tracing. Faster testing means faster isolation from work mates & public.

Agree. UK has given out these test for twice weekly home testing and picked up 120,000 cases this way. It also reduced burden of memory for contact tracing questions if tested regularly.

Indeed but TGA said they were not confident about how the public would cope with a + diagnosis. UK has used these free of charge to the community for home testing since April and identified 120,000 cases that would have gone undetected.

Employers should be daily screening their asymptomatic essential service staff (eg delivery drivers, grocery store workers) who work together & with the public. Repeat daily tests is superior accuracy compared with no PCR or infrequent PCR testing.

Suggest you have it handy in ready in case you need a coffee. Also keep handy for pack-gatherings and keep doggie away from cats (infected cats may spread COVID! 🤣).

Masks are part of prevention. Dan Deere (water research) & I had fun “A mask.Don’t leave home without it” “If it’s-not-on-outside it’s-not-on” “If it’s-not-on-shopping it’s-not-on“ “If it’s-not-on don’t get on” “No sign-in no dine-in” “Scan the QR so we know where you R”
