Perspective:
The AZ phase III data does not have sufficient events in the >65s to judge efficacy in that age group. US, Germany and France are not using it in older patients for that reason. (US have declined to even consider it for any ages pending further data)
The company has proposed bridging to younger patients through a phase II study which shows equivalent immune response across younger and older subjects, rather than direct efficacy. The UK, the EMA (European Regulator), India, and a number of other juristictions have approved it on that basis, although a full phase III dataset would be more normal.
Neither approach is unreasonable, it's a judgement of benefit vs risk. I'm glad the UK have taken the approach they have personally, but I don't think other judgements are necessarily politically motivated.
We will have real-world data in the next 2-3 months which it's unlikely, but possible, will make our decision look wrong in hindsight. Equally, more elderly French, Germans and Americans may die as a result of their conservative decisions on risk.
