I think this "we are better than you" is becoming ridiculous. Europe and UK are neighbours with enormous amounts of trade and people moving and holidaying between us. What happens in the UK affects Europe and viceversa.
There is no question Europe has experienced a vaccine shortage but much of the problems have been resolved and as new vaccines are approved, we will catch up.
There has been, as I said previously on another thread, different strategies used in different countries. The UK needed to get the first vaccines to most of the population to deal with the near collapse of the NHS and amount of deaths. Spain, the country I'm most familiar with outside Australia, is achieving the same objective with a much smaller part of their population fully vaccinated and without the need for a national lockdown. In fact, the only autonomous region still with over 300 cases per 100,000 is Madrid but is down 43% in the last 14 days. Madrid however is a special case, they are the only region in Spain where museums, theaters etc are still open with safe distance policies. Same as bars and restaurants with a curfew of 11.00pm.
There are problems with the Astro-Zeneca ONLY because the company (NOT the UK) never tested enough people in the older groups. There is not "we don't want the UK vaccine because is British" as too often is spin by tabloids in the UK. It has never been Europe against the UK, just Europe taking a private pharmaceutical to account on the contracts they signed with the millions of European public money invested.
Each country has the right to protect their population on the advice their health officials received. As long as we all get vaccinated this year and this fucking virus becomes "just another virus", we will all win.
