The plan is clearly to stymie our vaccine rollout programme until the EU nations catch up. The EU and its member nations have enough resources between them to ensure an effective rollout. The fact is they blew it because of prevarication, arguing over prices (falsely believing it had the weight to control the market), and ridiculous bureaucracy.
I'm fed up with hearing of accusations of "vaccine nationalism" and "we're not protected until the world is protected." The second, particularly, is nonsense. Whatever protection the vaccine provides, the sooner individuals have it the better. I can imagine if the situation was reversed that the usual suspects would be howling from the rooftops of the virtues of the EU, the UK was mad to leave and it must catch up as soon as possible. Nobody would be suggesting the EU delays its rollout until the UK catches up, let alone be considering to enforce such a move by blocking exports to the EU.
Mrs Von der Leyen has thrived on being a mediocre politician. She needs to concentrate on putting right the EU's collective mistakes which has led to their pathetic vaccine rollout programme and not think of doing so by jeopardising te programmes of other nations who have done rather better.
