Vaccinations not enough. “vaccinations have been highly effective at reducing severe disease & deaths, they are much less effective at reducing the risk of getting long COVID following COVID infections. Most effective way to avoid getting long COVID is not to get COVID.(Fig 1)

The day Aust reached total 1 million cases its instructive to review last 2 years. Cases/day & Deaths/day highest over first 11 days 2022. Outbreak management has failed - needs free RATs, RAT result-App, all boosters & kid doses ASAP & $ sick leave support.

Boosters at 4mths (Jan 4),3mths (end Jan) should now be prioritised for those with 2 doses of AZ (after 4 months v.low protection against Omicron). International positive cases now match when India ban was imposed. Travellers need booster & rapid antigen test on arrival to Aus

Omicron is associated with high ability to evade immunity from previous infection doi.org/10.1101/2021.11.11.2… & potentially vaccine immunity. Israeli experience with Delta showed immunity waned at 4-6months. With risk from Omicron circulating we should boost around 4mths after dose 2

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.

"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.

Herd immunity(HI) a big ask but we can do it. Countries targeting HI as % of total population= Israel 66%, Singapore 75%, NZ 78%, China 70-80%. We should target minimum 67% total pop, preferably 80% (for Delta). HI includes 12-18years & should target 100% vaccination of 60+years.
