No because I've gotten the flu some years long before I ever tried a flu shot. The two times I got the flu shot I got the flu for sure that winter, when I didn't get it the next year I had maybe a 1/4 chance of flu since then. I actually went flu free for almost exactly two years after having the OG strain of COVID in November 2019. I keep my zinc levels up and the last flu only bothered me for a few days.
