Norway is one of the few countries where it makes sense to be extra cautious, as they have excellent medical records and strong control over virus transmission.
It's absolutely mad for Italy, Austria etc.
But this is not a surprise: countries that handle the pandemic well (evidence based rather than populism or dogma) continue to manage the vaccine rollout well, and vice versa.
Yes, the US and the UK have done a good job ordering vaccine. The UK learnt a lesson about outsourcing and used the NHS for vaccine delivery. Delivery in the US is still shambolic, they just have an enormous supply.
