All my immediate family now has either first jab of AZ or has had Pfizer now. I am under 40 so still don't qualify.
I know many over 70s who are waiting for other options like the so called "patch" in development. These people are going to be what keeps Australia from returning to anything like normal.
Pre-emptive victim blaming. (Not by you @Mr._Lane - not even you @RTT_Rules
6 weeks ago no-one could get vacced for love nor money. Now, a handful of state clinics can't get over 50s to share a needle, and it's all their fault.
This is what I genuinely think is happening with our Vacc program:
Mid Last year Gvt committed us to AZ in advance of results of clinical trials. I think that was the RIGHT decision at the time. CLS could make it, no IP issues, used traditional Vacc methods and no bleeding edge tech like mRNA. I want to stress, I think this was the RIGHT decision at the time.
Some PZ was ordered as a stop gap until domestic AZ production came on-stream mid this year.
Dec last year clinical trial results showed you-beaut new American Vaccs are really good, and AZ about as good as the Flu vacc: works a bit, not against all variants, better than nothing.
Early this year I expect the (Fed) Gvts advice changed: we need more - much more - mRNA. But rather than suggest they "made a mistake" (even though IMHO they didn't), nor concede the late pivot to Pf has greatly delayed our Vacc rollout, they've used the blood clot issue with AZ to limit it's rollout to over 50s who "they" hope are far less mobile and not so important for achieving HI.
If it works, great! But opening boarders still can't happen until early/mid next year. If there is a big outbreak in the mean time, no biggie, in fact it's an opportunity to relax border controls, and as anyone who dies will likely be over 50, it's all their fault for not being vaccinated.
That's where we are now: deflecting blame until all those who matter (over 50s don't change their vote /s) are properly vaccinated later this year or early next.
ATM, the UK has relaxed it's lockdown (once COVID got to a "manageable" 2000 cases a day), but saw an immediate surge of cases AND hospitalisations and deaths. The (poor) results from their "one dose" strategy prioritizing the vulnerable are hardly surprising, entirely consistent with what we know from the clinical trials, and what happens when you use a medication against the manufacture's advice in a way that hasn't been properly tested: it doesn't work.
(AFAIK) Many European countries are grappling with what to do with all their people who've had one dose of AZ: continue with AZ/AZ (eventually, shorten the gap), or go to AZ/Pf.
For the moment at least, Pf appears to be suppressing COVID through herd effects in Israel and the USA. I'll be very interested to see how the UAE goes with it's 50/50, Citizens/slaves, Pf/SinoPlacebo strategy (/s @RTT_Rules
, I'm joking!) Of more interest is Pf vs Delta (formerly B1617.2/India). Based on the reported R0 and Ve of Pf vs Delta, it'll be a near run thing.
The other big unknown is how long the Vaccs last. (AFAIK) efficacy is a strong predictor of endurance. The CEO of Pfizer has announced he thinks all their customers will need a booster every year (I have shares, Go Pfizer !!) (AFAIK - ie I can't be bothered trying to re-find and link the study from Brazil which shows this) natural infection confers some protection for about 7-8 months. On that basis, we can expect (a full course) of AZ to last between 8 and 12 months (but no-one really knows). People in Oz will still be waiting for their first doses of any
vaccine in March next year, at the time it wears off in those vacced with AZ today.
So, IMHO, before we can even consider relaxing border controls, we're going to need everyone 12-50 vacced with Pf, and most over 50 re-vacced with Pf next year, (if we're lucky with only one dose). In the meantime, (IMHO) AZ is something of a national placebo, offering peace of mind that we have a vacc program, and soon everyone will be "vaccinated" - as distinct from our population actually protected. Don't get me wrong, AZ clearly works, and clearly lowers the severity of COVID infections (except against Beta, but she'll be right), but it's not the way out of the pandemic.
Further, there is a good chance everyone in Oz will need to be boosted with "New" Pf (or New Moderna, New Novavax, New Coke) by then, even if it's just to hold Delta (the disease not the singer, but they are easy to confuse). Unfortunately no-one even seems to be considering - much less planning - for it. Clearly we have to wait for it to show up in the focus groups.
