It has happened already. First the Germans including Merkel bad mouthed the vaccines. They had a surplus of vaccines build up even though few had been vaccinated. Then Macron of France got on the bandwagon and called the AstraZeneca vaccine barely effective.
This has been a cynical ploy. If you have messed up big time, and they have, then you reduce demand, and hey presto, the shortage disappears. If you are a Eurocrat in that dreadful organization, it makes perfect sense. Ursula Von der Lying, the president, bears huge responsibility for the fiasco, but refuses to resign. She has no electoral accountability to EU citizens whatsoever. Only 32% of the UK population are now in favor of rejoining the EU. This number continues to fall.
Here are the European vaccination rates as of March 9. The UK is vaccinating at least 250,000 a day and sometimes 500,000 a day. They will be heading to 50% very soon, and are aiming for herd immunity no later than June 21 with cancellation of all restrictions. The EU on the other hand leads with Malta, a tiny Island that got extra doses by mistake at 23%. Hungary is next because they bought Sputnik 5 and Chinese Sinopharm off the ration. They are at 15%. Denmark are at 13%, Norway at 11% and Iceland at 12%. Norway and Iceland are non EU, but I believe joined the EU purchasing consortium, but I could be wrong about that. Germany has done 10% and so has France. Germany has also started buying off the ration.
Italy has done 9.5% and confiscated a large quantity of AstraZeneca vaccine made in Italy that Australia had already purchased.
Irv, you still have a lot to learn about the EU. I have been trying to inform you of the incompetence and worse, of the EU for years. If you really understood the EU, these actions would make sense and be predictable. The EU has not been known by many in the UK as the EUSSR without good reason.
