After the wild "let us suspend AZ and let us restart it in two days" ride, it will be much harder to get AZ into arms of European patients. Even here in the Czech Republic, where AZ wasn't suspended, the reverbations in the public are stark and all kinds of half-baked conspiracies started circulating. (An example: "Germans want to get rid of a junk vaccine and force it on us Slavic untermenschen, while they will only use more expensive and better Pfizer for themselves.")

(b) This wasn't without reason. AZ has significantly more severe side effects and is less effective.
(c) That said, I'd certainly still take it, it is highly effective at preventing the worst outcomes.
(d) That said, the whole "consumer confidence" narrative is a canard. Its effects don't come anywhere near the effect of the delivery shortfalls. It's so totally ridiculous that it does make me wonder where it is coming from.
Now why might they have only used half so far, of a vaccine requiring two jabs?
They are keeping the other half for the required 2nd jab.
For some bizarre reason, they are not confident about timely delivery of future supplies.
