This was the situation on Monday in the UK
More than 46.5 million people - 88% of all UK adults - have now received a first dose of a vaccine and more than 37 million people, or 70% of all adults, have had a second.
The Spanish article talks about herd immunity at 80% full vaccinated, but there will be adults who have had Covid are not double vaccinated that could add 9% to the 70% figure. We could explain why infections are dropping in the UK. I don't buy the infections are dropping because its the school holidays and there is less testing. Note the difference in numbers. UK its 37 million Spain its 26 million - which means Spain is has approx 28% less people?
