You do have to wonder if some of this is politically driven. Germany are losing hundreds of life's a day, while in the meantime the UK has administrated 23 million doses (not sure the ratio of those that were AstraZeneca) and not recorded a single fatality or adverse reaction and are seeing infection rates / deaths drop. I can understand caution under normal circumstances, but nothing is normal right now.
