Australia at major risk from resistant COVID variants by late 2021. COVID research update
COVID is far more dangerous than I realised. 5th April 2021
Until I watched Anne de Gheest’s 2/April/21 COVID research update. @ADeGheest https://www.youtube.com/watch?v=5H_EYAMnGp8 last evening (3/April/21), I was starting to feel that by mid 2021, the Western developed world would be starting to “get back to ‘normal’”, because COVID vaccinations were rolling out very rapidly in the USA and UK and Europe was rapidly escalating their vaccination program.
Now I am starting to think that it might be something closer to end of 2022 or maybe even later - and the cost to deal with COVID will be far higher than I had been expecting.
And I am now realising that Long-COVID maybe an even bigger problem than the initial COVID inflections.

Anne's 2/April/2021 Covid epidemiology update is here. https://www.youtube.com/watch?v=Vkv-nxKG-hc
In the epidemiology update, Anne is saying that the Brazlian P1 variant is circulating in California. She also talks a fair bit about the UK variant driving the COVID surge in the USA's north eastern states and in mainland Europe.
This is also worth watching

You might also note Eric Topol co-authored article in Nature Magazine ( https://science.sciencemag.org/content/371/6531/759/tab-pdf , https://twitter.com/EricTopol/status/1379159370471153666 ) where Eric explains that while the initial COVID virus was “evasion-light”, thus enabling vaccines to be developed very quickly, there is a very real risk that a COVID variant that is “evasion-strong” may emerge, so that COVID may develop what is known as “immune escape” – very serious. One of the real risks is “Laboratory studies suggest the potential for immune escape with at least one of these (UK, South African, Brazilian) variants”.
On Thursday 8th/April/21 it was announced that all people under age 50 recommended to have the Pfizer vaccine
On the night of Thursday 8th/April/, 20million more doses of Pfizer vaccine was ordered - for delivery in Q42021. This necessarily will slow down the rollout of vaccine to Australians. And maybe the Q4 Pfizer vaccines will be an updated vaccine to deal with the South African and Brazilian COVID variants more effectively as well. With an mRNA vaccine, Pfizer/BioNTech should be able to deliver an updated vaccine well before then.
And Australia is now going to keep its borders closed until 2022.
I think these quick decisions are a rational reaction to the latest COVID research above that I published on 5April2021. So I think that is a positive thing.
We were also reminded on Friday that Australia also has 51million Novavax COVID vaccine ordered with expected delivery (assuming approved) commencing in June 2021. And testing of the Novavax vaccine seems to be indicating similar levels of effectiveness as the 2 mRNA vaccines at this point.
Clearly, Australia must continue to adapt its COVID strategy as the nature of the COVID problem changes.
But we can already see that in Q4CY2021 at the latest, Australia needs to be reimmunising older Australians with updated vaccines to deal with the latest COVID variants.
Vaccinated Australians will be able to travel overseas.
What has gone wrong with Australia's vaccination program? The rollout is very slow. As Normal war points out ( https://www.abc.net.au/radio/programs/coronacast/lets-push-the-reset-button-on-the-vaccine-rollout/13298272 ), what this is likely to mean is that over coming months, most developed countries will be opening international travel (particularly for vaccinated travellers), but Australia will still be comparatively un-vaccinated ..... This creates 2 problems. First, other economies will be getting back to "normal" while Australia cannot. Second, Australia's population will be very vulnerable if one of the new variants gets loose in Australia.
It is the new and coming COVID variant's that wil now dictate how this pandemic unfolds, but it now seems the humanity might be fighting this virus for at least some years yet - and it could get very ugly yet before it is over.

6/4/21 Moderna dramatically increases COVID vaccine production.
Adenovirus vector COVID vaccines may all have a "blood clotting issue".
Both the AstraZeneca COVID vaccine and the Johnson & Johnson COVID vaccine are adenovirus vector COVID vaccines.
"Cerebral vein thrombosis (CVST) w/ J&J vaccine in 6 young women (ages 18-48) among 6.8 million dosed follows the pattern of Astra Zeneca (222 cases in 34 million of very rare clotting events), implicating adenovirus vector link"
"Federal authorities on Tuesday recommended that states stop using Johnson & Johnson’s Covid-19 vaccine while an investigation is conducted into six serious cases of clotting problems — one of which was fatal — that were reported among women who received the vaccine. The blood clots are similar to those reported by several European countries after use of AstraZeneca’s Covid-19 vaccine. And they are similar to an event that occurred during Johnson & Johnson’s U.S.-based clinical trial, an event that led to a temporary pause in that trial last fall. "
Second Australian case of blood clots likely linked to AstraZeneca COVID-19 vaccination, TGA says
"The Therapeutic Goods Administration (TGA), in a statement, said the woman was in hospital receiving treatment, and was in a stable condition. A panel of expert advisers to the TGA met last night and found the blood clots were similar to cases seen in Europe and the United Kingdom, because it included significant blood clots in the veins and a low blood platelet count."
"AstraZeneca blood clot concern sees Australian government name Pfizer as preferred vaccine for adults under 50"
"Evidence from more vaccines that override concerns about the B.1.351 (501Y.V2, identified in South Africa) variant, which has the most immune evasion property of any of the variants seen to date (via lab assays)
"The spectrum of immune evasiveness compiled from lab study reports, with B.1.351 having the most observed to date, yet responsive to vaccines, and cross-reactivity observed for antibodies vs. this variant to others"
Useful summary of the war with COVID variants.
Eric Topol - "Variants May Not Be So Scary"
The United States is starting a 4th wave, predominantly related to the B.1.1.7 variant (identified in the UK). But here's why I'm optimistic
