First it was efficiany with elderly in the study, were the numbers were totally misunderstood. Then it was overall effectiveness, then prevention of severe cases. The list goes on. In the meanwhile, the press is reporting every single rash people get with AZ.
EDIT: Just checked, they found 7 cases of thrombosis in the brain, out of 1.6 million vaccinated people. Well, we'll see how that develops.
I don't think they are trying to get revenge. They are trying to cover for their own failings. By any reasonable means, the vaccine rollout in continental Europe in relation to the wealth and logistics available compared to US/UK is a complete failure.
Except, you know, order enough vaccines for their population. Other than that though, everything that they can!
And yes, governments are doing everything they can. And the screw up with vaccinations. No idea why, because I don't have all the details, but maybe AZ is just coming in time to have been 1) a good scape goat early on when one was needed during the frustration with vaccine deliveries 2) bad at PR 3) earned a bad rep and now everybody is over cautious. And public / media pressure isn't really helping.
