alistair given how quickly covid spreads and how long it takes to modify a vaccine, personally think the only smart way forward is to completely shut the borders… you can probably make a case for travel to places that are covid free like the Maldives or Seychelles, but not beyond that.
At the end of the day, I think it comes down to holidays and subsequent variant risks, possibly leading to further lockdowns… or shutting the borders and a normal life here… crap as it may be not to go on holiday, bit of a no brainer for me.
