To be fair, I've found a quote from Patrick Vallance (Scientific Advisor) that could be misconstrued.As usual 'dick head', your link makes my point.
It is a report by some journalist claiming (mis-understanding?) that some Govt. scientists were actively advocating 'herd immunity' as a 'policy'.....
.....which makes no sense - as scientists use 'herd immunity' to describe a natural phenomenon.
If you can produce the Govt. 'manifesto' that declares as a POLICY 'herd immunity' please do so.
He said that it would take 60% of people to contract the virus for there to be 'herd immunity'.
BUT, the context is that currently there is no vaccine (which is normally the means of creating herd immunity) so Vallance was merely stating that, sometime later this year 'herd immunity' would be reached naturally via infection, rather than by vaccine.
On the one hand Vallance could have been clearer.....
On the other, journalists are notoriously bad at science ( and maths).
