I'm pretty sure it was approved only based on testing done by AZ themselves. So there were no "independent" tests when it was approved.
As I said before, that's normal procedure for any medication, so we're arguing about the definition of "independent".
Btw the case in Italy was autopsied and found to not have any blood clots.
Edit: found a link in english for Italy
