stats
The statistics seem mildly bad to me.
A few days ago, infections were about half alpha variant, half delta variant. The delta variant seems to spread more rapidly.

Page 39 in this report says that two does of vaccine are 79% effective at protecting against the delta variant

After initially giving an incorrect statistic, the chief scientific adviser says that 40% of the people who have been admitted to hospital have had two doses of vaccine.
To me, it seems that the numbers indicate that filling stadiums and concert halls with people is still going to result in lots of infections in people who go home to places all over the UK. Vaccination reducing the chance of transmission by a factor of five is not enough.
