What happened, much as I prefer him to any other choice, is that Boris was exceptionally slow in responding, or stopping people entering, what is basically a small island. Vaccine rollout was great, just very late by that point. People "were" sent back to care homes, having been given covid on the way. And he is now destroying them further, by attempting mandatory vaccines, for one set of staff, only- who will all move to NHS work, where it isn't "necessary".
I'm sure there are.... reasons... just cannot imagine what.
