Whilst things are not “back to normal” generally most of UK is open again now.
Numbers of infections in UK have been rising as a result of the reopening but now seem to have plateaued again.
Numbers of hospital admissions and deaths as a proportion of new infections are much lower than previous waves.
The reason is simple and easily explained:
It is summer and infections have a history of falling at this time and probably more importantly so far, more than 46.8 million people have had a first vaccine dose - nearly 90% of the adult population - and more than 38 million - over 70% of adults - have had both doses. https://www.bbc.co.uk/news/health-55274833
