A pretty balanced overview of the "UK vs EU vaccine" shitstorm, as seen from a side (Ireland).
I can just add that even this very balanced article misses one important detail when it speaks about "European leaders".
There's "European Union", a single political body composed of 27 member states, which basically said "AZ is safe" (EMA). Then there are 27 members, the national governments of the EU, a few of which were spreading FUD.
But these are distinct bodies!
