Have you read the reports of the trial dosages? 3,000 people got the wrong dosages. Apparently these people were better protected but really that's quite concerning that something that should be very carefully controlled goes so wrong.Astra Zeneca's behaviour has been exemplary.
A global company that could have made a financial killing out of this pandemic and yet here they are producing a safe, effective vaccine at the lowest cost and on a no profit basis with the objective of maximising the distribution to all countries affected.
Good on 'em.
I give them credit though for being open about it, and for making a good decision when they found about it.
