Az just announced they are doing a further international trial on the 0.5 then 1 dose of theie vaccine
presumably sample size wasnt enough
Posted an article on here last night from wired.com which shared concerns about the AZ results, and got met with pretty short shrift tbh with people dismissing it as rivals putting it down. Sadly, it looks like the concerns in that are true. The 90% claim came from a group with no one over 55 years old, which to be frank, is a bit ridiculous. Anyway, it's reached mainstream media now, so the retrial doesn't surprise me:
Doubts over Oxford Covid vaccine after it 'only worked well in younger people'
It has now emerged the smaller group of less than 3,000 out of 24,000 trial participants on the half-dose-full-dose regime - which recorded the 90% effectiveness rate - were all under 55

I truly hope, for all our sakes, they get their act together as we all want to be out of this. Feels a bit shambolic with the accidental doses and averaging efficacy across two totally different kind of control groups with differing ages, which seems an incredibly unscientific thing to do.
