Immunity not having challenges, especially early in life, is a sure recipe for a miserable life full of allergies (and probably more, autoimmune problems are a vast domain).
Not sure I would want to take a small risk of topic discussed with almost sure chance of this. Maybe some form of risk is unavoidable, and part of life. Of course only till we fully crack our dna manipulation without any side effects, but thats 22nd century stuff at best.
Environmental, non-disease challenges are important to develop proper immune response. Catching the flavor of the day does jack all, and might actually prompt some autoimmune responses and lymphomas (due to the increased activity of the immune system in response to infection).
People who never acquire a chronic herpes zoster infection are highly unlikely to benefit from a shingles vaccine with respect to this sort of dementia.
