AZ stuffed up about November last year when its final trial was not accepted by the FDA due to not enough over 60s being included in the cohort. That is when the media first latched onto it, and then they followed up when it started having the clot issues. AZ is partly to blame for the media issues because of how they handled the final trial. They still haven't bothered to try to re-certify with the FDA as they really don't care, hence why its not available in the USA. The issue the feds had is that they put all their eggs in the AZ basket and didn't want to bargain with the other makers. The UK, Europe, USA all had large amounts of doses from at least 2 or 3 manufacturers. Australia was left with AZ and a dribble of Pf due to the poor planning at the start.
BTW Fiji has been using a lot of unwanted Australian AZ to get its population up above 50% DD. I found this amusing FAQ note in the Fiji's Department of health;
Is the COVID-19 vaccine evil?
This claim has no scientific basis and is not based on fact. What we do know is that getting a COVID-19 vaccine can help protect you and those around you against the COVID-19 disease.
Can science prove a vaccine evil? or not...
