Being in healthcare field for many years, it was almost the default that I would get a flu shot annually, unfortunately one year I developed Guillain-Barre syndrome with fairly significant paralysis, I subsequently avoided taking the Flu short the last 20 years. My wife an I rarely get sick, but now that we are north of 65 will need to reconsider. I recommend Shingrix for most people, it is very active and the chance that one gets Herpes Zoster increases as one gets older. Make sure you get both Shingrix vaccine doses.
