Yes, that is a spanner in the works. I have immunity issues and can't be vaccinated, so I've been at home since March 2019. If it weren't for the internet and wonderful Antiquers friends, I would have been climbing the walls. Rapidly. Much more contagious than the other variants. The good thing is that it doesn't seem to cause as much havoc as the others. I think Covid mutations will slowly develop into something like the common cold, which has happened before with extreme viruses. Could take a few years though.
