I know I've been overly optimistic about the vaccine and restrictions left, I agree about the change in government tact about the need for restrictions.
Seemingly all of adults will be vaccinated by May, so if the government thinks they're under pressure at the moment to lift some restrictions, wait till there are a handful of deaths and cases like summer, where there was the odd day with no deaths (not reported deaths). They'll really struggle to justify restrictions, and quite rightly.
If you want to look for positivity, a real world study shows that the cases in Israel have dropped like a stone, and now they're saying they've done all the over 60s, and the vaccine works.. this is despite some rather well attended funerals.. I would suggest that the world is watching
