Sanity tax has nothing to do with the EU. Actually, I am from a working class background and I discovered "period poverty" issue in the British newspapers, astonished it could be a problem in a rich country like Britain.So far we are a million miles ahead of the EU with vaccinations and been able to stop sanitry products being taxed as non essential, so that's a couple of positives of Brexit already.
As for the covid vaccine, it's only a few weeks' difference. And most people are in no rush. The worst is France. Only 4 of ten people want to get vaccinated against covid. Antivax conspiracy is powerful.
