There are clear signs or more clearly said facts from UK/Israel data: Pfizer/Astra do not protect from CoV-19 Delta. UK has > 18'000 cases and is now fully engaged in a 4th wave.
The two vaccines do also not protect from death from Delta at least not better than taking no vaccine. The only good news. Delta seem to be the harmless variant we all wait for, that gives us a free of cost/risk immunization!
I just wanted to point out that these comments from W here are 100% factually wrong.
UK data shows both Pfizer and Astra vaccine give very good protection against delta:
https://www.nature.com/articles/d41586-021-01696-3
Pfizer 2 doses (88% protection, ) Astrazeneca two doses (60% protection)
Against death the two vaccines protect by a factor of between 10 and 100. thus 1/10th to 1/100th of people die compared with who would have without vaccine.
thee is research, but more dramatic is the data on cases and deaths. Deaths lag cases by about 3 weeks but even so the uptick in UK infections has caused a muhc smaller uptick in deaths - for accurate data we must wait a bit longer.
Delta a harmless variant? 100% false. It spreads more easily. it appears to have spike modifications that make it more efficient at entering human cells. It makes people sicker faster (as you would expect if it is better at infecting cells).

it is quite simple: to maintain Wyttenbach's false view that delta is harmless you must also maintain his false view that vaccines do not protect the population...
