In reply to Chopper:
The vaccine will help bring the current pandemic under control bringing healthcare back from its current point as almost a one disease service running on the brink of exhaustion. Eventually we can release lockdown as the vaccination takes over controlling healthcare overload.
There could be new variants of the virus out there that the vaccine doesn’t work against. If we allow those to spread in the UK, the vaccination doesn’t control them, and they spread exponentially once control measures are released, and its back to healthcare overload and lockdown.
One such variant is already circulating in the UK; hopefully it’s still partially covered by immunity from past infection and from the vaccine. We need to eliminate or control that variant locally as a priority. This is here because during 2020 we had the misapprehension that travel is okay if both ends are equally infected. One of the reasons it isn’t okay is because the probability of a variant getting loose goes up over larger interconnected areas. Cut travel links and it’s more contained.
At this rate I don’t see how travel without managed isolation and quarantine is going to be sensible before 2022.
