I took the shingles vaccine (at the same time as flu and a covid booster). So I probably won't get shingles. And even when the flu shot doesn't give me immunity, it still reduces symptoms that it's a couple days in bed, watching movies and drinking juice.
I've already beaten the odds -- because I managed to not get the early, more debilitating strains which caused more long-haul covid. Medical articles I have read suggest that the longer we Covid-dodgers hold out, the better our outcome will be should we ever catch it.
I also haven't had the common cold or anything else since the pandemic started. It's been a welcome change.
