I think price + unproven was a big concern for the less wealthy countries.

One has to keep in mind with the EU that we tried our best to avoid splitting the continent into winners and losers based on which countries were the wealthiest. Unfortunately we ended up being on the losing side together, but the driving idea wasn't wrong. :-)

It was also not wrong to want to do a complete instead of emergency certification of the vaccine or pressing e.g. Pfizer to take responsibility for unwanted side-effects. Other countries risked more and it seems that they were favoured by fortune.
