FWIW I'd like the roll out to be faster but I'm not too concerned yet. It is a bit disappointing that it isn't faster already because the logistical challenges they are experiencing could have been foreseen for very many months. There are no surprises here, including the need for -70 storage in some cases. Maybe the 15 min anaphylaxis wait was unforeseen but not unforeseeable for those who wargame this kind of thing.
If we don't see a rapid ramping up of the vaccination rate around now then there will be a cause for concern/complaint.
It is fair to compare between countries but you need to compare apples with apples. We can, and have, praised the regulators for being speedy with the first two options. Obviously that gives the UK a head start when counting how many jabs have been done on any given date. However, the success of the roll out operation is a completely different question. Whether we have done relatively well under the challenges that will have to be met by all countries, has to be answered by comparing what percentage of the population they have jabbed starting from Day 1, which is different in different countries.
