As Skawkbox article linked by Clark is spot on. I have always believed that the government has never abandoned the policy of herd immunity just stopped talking about it, It explains the way that they have behaved throughout, abandoning early testing in the community, not providing PPE, ignoring the care homes, and the half hearted ‘lock down’ which has effectively been diluted further..
But I also do not understand why the basics of public health measures used for combatting epidemics have been abandoned for the sake of listening to non-medical experts with their modelling fetishes. This has detracted from real science I am afraid, and that is why the medical advice has been so sidelined and so shambolic.
For what is essentially a respiratory virus, the emphasis from the outset has been on hand washing. OK that is important but only as secondary to limiting the virus leaving the respiratory passages and landing on an object. The fact that masks can also do this also by preventing wider spread of aerosols has been ignored and when debated, has been even suggested to be possibly dangerous because you can touch your g=face more. What a moronic excuse, if you have already washed your hands you can touch your face if you want!!!!
Then there is this idiotic phrase: test track and isolate, which should revert to its original proper form of the purpose of widespread testing and contact tracing, which is to QUARANTINE, I am sorry I have to shout, but self isolation and quarantining are two different animals altogether. A quarantined person is totally isolated and cared for by people who must themselves be protected with PPE and totally looked after for FOURTEEN DAYS, yes that is right 14 DAYS.
I think that the scientific community especially the scientific advisors to the government are complicit in this, maybe indirectly, because they have been told that there is no money for PPE and there is no money for providing proper quarantine facilities.
