I am not here to tell you whether you need to take a flu shot or not, I am simply going to tell you my experience. Although I was vaccinated as a little kid, growing up I didn’t take flu shots. I only caught the flu once in my life, it was awful and I was in bed for a few days, but that was it!
A few ago years my father wanted to get a flu shot following his doctor’s recommendation. I thought it is not gonna hurt, maybe I should too. However, I spent that winter going through several semi-colds if I can call it that. I would feel weak, runny nose and teary eyes, sometimes a little fever. At first, I didn’t think that it was related to the flu shot, but a couple years later I had to take the flu shot again, and I got the same bad winter. That was it for me, no more flu shots.
