Aren’t they mostly using the Astra Zeneca one which has been shown to only be like 24% effective against some of the new strains? I wonder how many vaxxed people with Pfizer or moderna have gotten sick
Yeah efficiency of AstraZennica is between 10 to 22% against the beta variant
:covid-cool: :doomjak:
For the latter (AstraZennica) trial, an overall vaccine efficacy was reported at 22% and 10% against the South African variant, with B.1.351 making up 95% of the cases
Yes, good thing the Pfizer vaccine isn’t showing significant loss of antibody neutralization against the delta variant, isn’t it? It feels good to be an American 😎
It’s a fall from 95% to 75% effectiveness, which is manageable at least. The phizer vaccine is showing a similar response to the delta variant as it did to the beta variant. The real worry is countries that use the AstraZennica vaccine, because if that responds to the delta variant in the same way it responded to the beta variant, it becomes practically useless with 10% effectiveness (see my other comments in this thread).
But what’s to say the same thing can’t happen in the USA in the future? As someone that has seen my country turn a shipment of vaccines back due to this, the situation is very volatile globally. The effectiveness of the Pfizer vaccine after two does still drops to 75% against the beta and delta variants. Obviously that’s manageable and no where near as bad as 22%, but it still shows how volatile everything is
