I dunno. I didn't think it was necessary either but that's what CDC suggests. I wasn't going to get it, but then my town went back to stage 5 and all this hysteria again. It seemed to bother people at my work and in my family that I wasn't vaccinated. So I just said fuck it and got it done because I was tired of people nagging me about it.
I guess it's given me a little more peace of mind. Having had covid and now had the vaccine I'm like not concerned with it anymore literally at all. Where as before I got vaccinated I had a thought In my head "hope I don't get it again". Not that I was scared straight of getting super sick, just the thought of missing work and being in quarantine would be annoying.
