Spreading orders across manufacturers was actually quite prudent. Sanofi's mRNA vaccine is delayed. We have no reaon to believe that is was impossible that the same could have happened to Biontech / Pfizer and / or Moderna.

Overall the EU ordered 4+ doses per inhabitant, incl. minors. That seems to be enough. Single sourcing is never good. In case of vaccines it would mean that a) vaccines are delayed b) manufacturing issues happen. Also ordering enough from each manufacturer would have blown their manufacturing capacites. The necessary capacity increases woud just have further delayed deliveries, as the Pfizer plant in Belgium shows quite clearly.

And yes, as far as I understood the AZ contract, alocations are the same for each EU memeber state. Proportionally of course, Germany will get more doses in absolute numbers than, say, Luxembourg.
