Got mine in October at my doctor's urging.
Anyone 65 or older should.
Granted my grandfather is 84, but he was one of those guys who never had it, grew up in crummy Brooklyn during the war, figures he has a good immune system, and his doctor given that actually told him to not bother. Four months later he ends up in the hospital with flu and superimposed pneumonia and was in there for weeks. It’s just not worth not getting it. If he succumbed I would have made it my goal in life to make sure that doctor never touches a patient again. Not everyone makes it through a wake-up call like that.
