A touch of vaccine nationalism (probably more verbal than physical) is inevitable now, at least to appease voters. However the complicated nature of supply chains can make this very counterproductive in the short term (because of critical component sourcing being hit in counter-measures) and longer term (because breaking commercial contracts at a political whim is the stuff of Russia and China, not safe investment nations). This is presumably why smaller nations such as Ireland and Belgium are so anti-vaccine blocking. It's a bit worrying when renowned Luxembourg wine expert Jean-Claude Junker seems like a voice for sense in EU circles...
