"circuit breaker" doesn't do anything to prevent things, with a doubling time of 2 days, all it does is move things by the length of the lockdown and a half - so 2 week lockdown, we're in the same place in 3 weeks, so presumably then there would be another circuit breaker?
And Indie Sage must know this - So they're just being dishonest in their desire, presumably because they think that a drip-drip dishonesty is the way to get agreement and support for their viewpoint, rather than simply being honest and providing their rationale.
For me, the "Zero Covid" people have been a disaster, we could've flattened the curve ensured that the vulnerable and even more were well vaccinated and had infection gradually cover everyone else, had we done that, infection+vaccine immunity which is very good at preventing omicron infection would've dominated now and we would have had a controllable wave. Instead we've got so many naïve people, including now vulnerable people with waned vaccines who can't get a shot 'cos we're giving more doses to the healthy 25 year old.
The NHS may well be overwhelmed now, but a circuit breaker isn't going to do diddly, it's a pretty long lockdown, with proper distancing measures. It may well be though that fewer people will die if we rely on infecting as many people in as short as possible time while the vulnerable boosting is still fresh - 'cos in a months time those 60+ peoples boosters will be waning. A Tough call, but a circuit breaker lockdown does f'all.
