I don't see why not. I am in the O.70 and vulnerable group (asthma), still waiting for vaccination, but it is complicated. OH is in his 80s with several vulnerabilities, but has now had both jabs.
As I recall, the whole point of the lockdown was to ease the burden on the NHS (which, quite frankly, should have been able to cope if it hadn't been cut so harshly so we have the fewest beds in Europe - but I digress and this is a point on which we feel strongly, .... however).
Since it is accepted that death rates and bed occupancy should/will decrease due to vaccination I can see no reason why the economy should not open up a.s.a.p.. OH has been vaccinated (2x) so should not occupy a bed, for example. Younger people are less likely to be seriously ill and need hospitalisation, so really can be mostly disregarded.
