indeed, we older generation (66 here) still had all the childhood illnesses, built up immunity, and then I cleaned houses for 10 years, got close to all the germs and never had anything serious. I heard that some shingles shots cause shingles, one friend had that, but there seem to be new ones that don't have it, they are all painful and I don't think much of any jab right now. No needles in me if I can avoid it! Well, I am a seemstress and that are the only needles I want.
