A few somewhat disconnected thoughts.
I am inclined to believe the consensus of scientific opinion. It may be wrong, but is likely to be much more reliable than relying on outlier opinions. Gupta sits comfortably in the latter group.
Suggesting lockdown does not work based on when cases and deaths began to fall subsequently is flawed. It is also a completely counter-intuitive. Partly due to the reluctance of the UK govt to act early, it is more likely behaviours changed in anticipation of lockdown.
Many suggested in summer 2020 that the Covid problem was over. They were evidently very wrong as cases increased rapidly from September, not helped by a mutated virus.
The base and best data is provided by ONS. Relying on some form of modified data set (time slipped etc?) simply confuses the issue. My instinct is to distrust conclusions so drawn.
The virus cannot be completely eliminated and will only become a "non-threat" with herd immunity. (70%+) Lockdown slows transmission but simply extends duration and economic hardship. The vaccine in supporting herd immunity now means duration may be less of an issue.
Implicit in less than 100% immunity is the acceptance that cases will continue to emerge. We need to be explicit about the acceptable level of infection and death. This is no different to other viruses - eg flu.
The government are being very evasive. As of now there may be insufficient data, but this should rapidly emerge:
- does the vaccine stop onward virus transmission
- what is the efficacy of 12 week wait for 2nd *** vs 2/3 weeks
- even if timing is uncertain - what are the priorities for relaxation
In any event when it becomes evident that the NHS load is declining materially, enforcing restrictions will become increasingly unsustainable.
