The list is not very long so far- but I do live in hope.

For Covid, any EU country could have chosen to go their own way on pruchasing the vaccines. You could argue that the disastrous situation with numbers in the UK currently, is the catastrophic failure of Johnson to lock in in time, on several occasions- based on the advice by all the medical associations- including recently over Christmas and even returning to school for just one day- one day to allow for super spread, just time enough. Nothing of course to do with Brexit or the EU.

And as said above, the EU provided massive funds to develop vaccines- which were developed and manufactured in EU. Even the so called Oxford massive is based on massive international cooperation.

But back to that long list of wonders. Please.
