What do you mean by herd immunity here, Bjorn?
Hey Carole! "Herd immunity" is their words. I understand it to be that *if* you can't get covid-19 again then any new infection introduced into the Stockholm area after May will peter out, making Stockholm intrinsically immune to corona
Does anyone know how long any immunity might last - and is that time span varied by the severity of the first infection. The more severe the symptoms the longer the immunity lasts etc?.
There is no proof that there is ANY immunity.
Herd immunity just means that the number of non-immune people falls low enough that the R0 falls to or below 1 & the epidemic ends. It doesn't require that individual immunity isn't eventually lost.
There can still be outbreaks, but they shouldn't become an epidemic unless immunity is lost.
Lol utter nonsense
