As I have previously written, while any country has a serious COVID-19 outbreak none of us are safe. And a lot of the supply chains which provide PPE, drugs and vaccines are international supply chains. So vaccine nationalism helps nobody.
This is illustrated by the fact that the AZ factory in the Netherlands whose output to Britain the EU is threatening to block depends on supplies from a UK company based in Yorkshire.
I welcome the statement by the Prime Minister last week, that Britain will continue to work with our European friends - and expect them to stand by their commitment not to place restrictions on vaccine exports.
