True. >Delta isn't an escape variant, btw, it's just a really fast worker. It's faster, more transmissable, infectious, shorter incubation period and a 1000fold increase in generated virus particles compared to other variants. But is also has mutations in its spike and nucleocapsid that warrant developing new vaccines, certainly when it's at the moment the dominant strain by far and even more virulent variations are…
As far as I know new vaccines may be in the pipeline, but the current vaccines work so well against the delta variant that it's not worth switching. It will take a lot of time to gather enough data to confirm any new vaccine as actually being better and safer than Comirnaty against Delta... Just saying "This vaccines was especially designed for this" isn't enough.
I disagree. The number of deaths has only been decreased fivefold when comparing first wave and 4th wave in Belgium. And yes, there are fully vaccinated people who are dying.
