An annually tweaked vaccine, rules but not locking down travel...
"Not locking down travel" and an annual vaccine is mitigation, not zero covid.
All the "zero covid" proponents agree that the UK borders need to be kept close for an extended period of time. This is something which I personally find absolutely unworkable.
Even if we stop tourism and business travel, we will still have issues of (i) the Irish border and (ii) freight. On average, 10,000 lorries pass the port of Dover daily. Do we really think we will be able to identify and isolate every single source of infection? Doesn't sound very practical.
Irish border is a separate topic which is equally complicated (as we know from the Brexit negotiations saga).
Mitigation/maximum mitigation strategy is a pragmatic solution given the UK geographical position and level of connectivity to the continent. "Zero covid", in my personal opinion, is an unattainable goal.
