SAGE might as well be disbanded if their suggestion to controlling the spread is to use a vaccine which there is no reason to believe reduces spread. This particular vaccine is only suitable to be used in people who are at higher risk of getting seriously ill from the vaccine rather than those at a higher risk of contracting it asymptomatically as there is no benefit from its use in the latter group.
That would mean no vaccine roll out at all then, as sterilising immunity has not been adequately demonstrated in any to date.
OTOH, giving the vulnerable (elderly, CEV and CV) a vaccine that makes their risk if serious disease broadly the same as the healthy u50 population, will save over 90% of deaths and countless hospitalisations. When there is spare capacity in NHS, we might be able to think about relaxing restrictions.
I can see why it is worthwhile.
Especially as it remains possibly that there will prove to be sterilising immunity.
