I think that it will be approved soon for over 65s in Germany, at which point her position should / will change.
Yes, of course I absolutely agree that she should not set the example of taking an unregulated med! In addition, it would be taking a vaccine from a German for whom it has been approved, when stocks are in short supply.
There is no other justifiable position. Put down your hate for a moment, have a think for a few seconds, and read more than the headlines.
The EU medicines agency (whatever they are called) approved the use of AZ in ALL adults as far as I'm aware. The fact that Germany and France have separate rules for over 65s implies they don't think the EMA knows what they are doing. There are also loads of unused vaccines due to low takeup in some of these countries, so she probably wouldn't be taking a vaccination off anyone.
