Id like to add:

The UK recently had a study that showed about 13% of London had antibodies (end of july) and 17% had it in mid May.

What isn't being talked about is that antiboodies don.t last long. About a quarter of Covid positive patients have no measurable antibody response, and even the hospitalised nealy all lost them by twelve weeks.

So the 13% currently showing antibodies is only those in about the past 8-10 weels. Anyone infected prior to mid may (the outbreak peak was early april to late may) isn't showing up in these antibody tests.

The bulk of the deaths happened before late may. This has important implications for mortality and how close Londn, and the rest of the UK, is to herd immunity.

It suggests IFR is between 0.2% and 0.1%, and immunity in London around 50%. The R for Covid is estimated to be around 2.7, which means herd immunity at around 65%.

London is probably very close to herd immunity.

People simply don't know you can be immune to something without antibodies, your bodies have a few different ways of fighting viruses. It's lack of education, such is purposeful at this point when we hear nothing but covid 24/7.
