Thread: On #Covid_19 #Covid quality of care, correct me if I’m wrong. 1/The Pfizer-Biontech vaccine (PBV) protects 2abt 94.5% of the recipients. It also protects ppl 50+ older 4a period similar 2younger. The Moderna vaccine (MV) provides abt 94% protection, but 4a seemingly
2/ shorter (how short?) period 4 50+ older recipients. The Astra-Zeneca vaccine (AZV) provides 70% or so protection all ages. PBV requires -70ºC refrigeration 2point of dilution, dilution within 5 days & delivery within 5 hours of dilution. MV can be kept at just -20ºC, hence far
3/ easier 2transport & stable for 30 days when so stored. AZV can be kept a refrigerator temperature (around +4ºC) (don’t know for how long), is cheaper, based on older tried & established vaccine technology. Now to get true herd immunity at say 63%, one either needs 90% of the
4/ppl vaccinated w/a vax providing 70% protection or 70% of the ppl vaccinated w/a vax providing 90%. In civilized countries w/full access & rational population, this shouldn’t be a problem. But in USA 40% & in France 60% of ppl don’t intend to get vaccinated.
5/One needs not be a seer to imagine, say in UK, AZV will go to Northern England & poorer neighbourhoods, while politicians & the rich get PBV. In Africa, they will get AZV when they get it, if they get it. Better than nothing, right? In Africa ppl get older HIV medication
6/long since abandoned in developed countries bcs of devastating side effects. The Great Rift between rich & poor widens during pandemics. Now, given large numbers of antivaxxers, irrational behavior, connection btw being antivaxxer & religious zealots, zealotry & right-wing,
7/requiring 90% of ppl immunized to stop pandemic seems rather illusory. Even requiring 70% looks like a titanic task. But in developed countries at least, administering those w/higher % protection would go a long way to help true herd immunity w/o millions of deaths.
8/So, PBV aside fm HC workers, politicians (old & young, of course) & the rich & famous (to give a virtuous example of courage, of course) should be administered to 50+ in developed countries at least, &/or MV to 50-, if we’re to truly stop Covid. 12/What happens if we go full
11/So say France & UK have both abt 67M ppl. If 60% do not get vaxxed in France & 100% were vaxxed in UK, the pool 134M is 80% vaxxed, at 70% efficacy one gets 56% overall, so no herd immunity. If UK got say 80% vaxxed, at 70% efficacy it would be 42% overall.
14/shines through ones again. How to preach by lack of example. Let’s hope at least vaccine allocations are done logically after that fiasco. If there is no real herd immunity & ppl keep travelling bcs they’re entitled to it & w/ “Covid fatigue”, virus keeps propagating, mutating
15/ & mutations are selected (Darwin takes no holidays either) which can propagate also among the vaccinated. Pls try 2adapt vax strategy 2deal w/logic, entitlement w/o brains, & antivaxxers threat or Covid will make 2021 look like 2020’s bigger & nastier brother. Happy New Year.
