I think it's down to every individual to do everything, within reason, to stop the spread of the virus. In the way that immunisation programmes only work when a certain percentage of the population are vaccinated. My DIL works for the NHS and my SIL has, unfortunately just started a new job in London and is commuting. I want to keep myself safe so that, if needs be I can step in for child care etc if I was needed. As has been pointed out before we just need to hold this back for as long as possible till the weather gets better. So much talk recently about Britishness and surviving things. Well, now's the time to do that, but not by poo poo'ing the situation but working, as a country to keep on top of this epidemic/pandemic until a vaccine is available. Oh yes, and also let's now start listening to experts, having been brainwashed into ignoring them.
