I think I will follow her PoV, for the trivial egoistic reason that if ever things turn out sour, it will be her fault, and not mine...
Way to go !
I myself will get a flu shot if I can. I have taken flu shots for the last 15 years or more, and don't see why I shouldn't get this one.
I never took any flue vaccine , and frankly cant recall in the last 10 years if I ever got flue.
Judging by the intensity of symptoms and recovery times, I don't believe I ever got anything else but colds. One time it got serious, but it turns out it was bacterial and I had to take antibiotics. My holidays were never ruined.
I see no much use to take immunizations only for the sake of it.
