Sample size one, but I’ve only had the flu once in my life (29 yo). It was back in 2007 when the vaccine whiffed on the dominant strain. I remember a two week period of little energy at first and then some energy I could expend on one task a day (for example, a shower). The flu is no joke, but getting it seems pretty hard from my anecdotal experience.
