I’ve never been vaxed and I had a mild case last year so I take this as good news. However, I have heard of cases where someone has had covid and is unvaxed, and caught it a second time.
Yes, very common for un-vaxxed to catch repeat infection.
Practice safe behavior always.
I had it a second time. But, the second time was more mild than a cold.
I caught the original Covid in 2020, then got Omicron earlier this year. Immunity does wane, but natural immunity to the old strains does not confer complete immunity to the new ones anyway. Corona viruses gonna virus and mutate away. It’s what they do.
