You are probably naturally immune now because you are in the world and out and around fighting it off with the healthy immune system God gave you. I understand the reason more older adults are getting shingles is because kids no longer get it because of vaccines and we are not being constantly naturally immunized anymore and the dormant virus reawakens. Most of my friends--have gotten shingles. Not sure how those new shingles shots are working. I’m not getting those either (74) But the Covid shots also made them more susceptible I read. It’s a mess for sure. I had Covid January 2021 before Covid jabs. I just thought it was a cold. That October I had antibody test showing I had it. Either in January or I built up an immunity by living a very full life and my immune system showed I’m ready to roll fighting the virus and variants off. Probably you too.
