> The issue is that extra 3-months of difference. Whether December 2020 approval was premature or not. And yet the USA approved the Pfizer vaccine on Dec 11, only a week after the UK. I'm not sure why there's a 3 month difference in approving the AZ vaccine, but I do know that the USA has some particularly draconian import rules on foreign medicines, especially untested ones, so perhaps extra bureaucracy, and almost certainly a different testing regime for medicines to the UK and EU. I'm satisfied that the UK MHRA and JVI have satisfactorily assessed the data from AZ, Pfizer, Moderna, (and Novavax). They're world experts in their fields.
