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
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).
Yes, and the key word there is manageable. Although the Pfizer drop off isn’t as bad as for AZ, this aspect isn’t cause for celebration for how the US might fare in the next few months. The recent federal position has implied that the government basically considers Covid to be done and dusted at this point. Sleepy Joe isn’t going to interrupt his hot wet American summer for anything.
The increase in reproduction rate through weakened vaccine response considered in the context of the abandonment of non-pharmaceutical interventions is bad news. Whilst this particular variant might not directly neutralise the Pfizer vaccine, given distancing and masks are now a thing of the past it’s still going to lead to more deaths and also increase the chances of a more effective variant emerging.
Of course it’s still a probability game and maybe we’ll get lucky and we won’t get an escape variant of significance for a long time, but the likelihood is increasing :sadness:
Rates are gonna be slow during summer regardless. Last time they fell almost everywhere when it got hot. I hope that if they continue to fall as rapidly as they are worldwide, rates should be low enough during summer that new mutations will be avoided while more people get vaccinated.
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
In my country we got the option to get the J&J vaccine, and when talking about the side effects the doctor was "as far as we know its these and these numbers, but the US system is fairly primitive, so its likely more"

Yeah efficiency of AstraZennica is between 10 to 22% against the beta variant

Yeah, it's not like that's all happening right now...
