I met a guy recently who is not having the vaccine because he has prostate cancer. He's not anti vax but has been told by holistic therapists that it's best for his condition if he doesn't. He's going off to a big club in London on Friday night and wants to see me on Sunday. I was initially ok with this but on reflection I'm not sure it's a good idea. I have luckily managed to avoid Covid so far and just don't know whether seeing this guy is bringing an unnecessary risk into my life? I've only met him once, he's perfectly nice, but I just don't know what to do. Any objective advice would be very much appreciated!
