The UK used AstraZenica. Last week, I read that the effective range is 4 months. So, there’s no shock.
The UK had large contracts with Pfizer, Moderna, and JOhnson and Johnson. The damage was caused by those too, not just AstraZenica.
The shock is that these aren’t vaccines that confer immunity - they are bioweapons with constantly sliding ‘promises’ that somehow never work out.
