from what I can gather, European suppliers are selling to countries outside of the EU despite failing to meet their contracted amount to various countries in the EU. As a result the EU is trying to get the company supplying Britain (which has a better supply of vaccines) to send some of it's supplies to countries in the EU despite the fact that it still hasn't reached its contracted amount with Britain.

or something along those lines, honestly I'm probably completely misrepresenting this by accident
