The vaccine rollout lads is very much its in infancy i would be cautious on declaring winners or loosers at this point. A number of twists and turns and peaks and troughs can and most likely will happen. We would all to well to leave the jingoism at the door.
Imagine tomorrow, the EMA says the efficacy of AZ isnt enough to be licensed for over 65s - its the first time AZ have gone for full market approval and its the first adenovirus vaccine and its a rigorous affair- that puts the Uk in a tricky position (hopefully not) and there could be criticism they jumped to soon if it came to pass. Do the EU pull up the ladder on Biotech - they got an extra 150 mill doses yesterday, Curevac are going to bolt after J&J shortly, the EU have a massive supply of that German Mrna vaccine (similar to Pfizer and Moderna), the UK haven't ordered any. If the 12 week spacing between jabs falls flat on its face with the Mrna jabs do Europe shut the door on the UK trying to buy more from the German companies.
Not saying any of the above will happen but an example of how things could peak and trough very easily, i think there will be many interchangeable periods of want and need during the vaccine roll out and we would do well to look at human aspect apart from a jingoistic one, its a huge pity in a way the Uk aren't part of the EU at the moment, we would all have that shared goal for each others welfare.
