Flu shots have variable results. You have to remember that there are many, many flu viruses, and the shot is only going to work against a very few of them (and perhaps only a single variant). Each year they attempt to "take a decent guess" at the flu that will be the most dominant and create the vaccine to work against that particular one.
It's (probably) not going to hurt you to get one, but simply washing your hands well is a far superior method of keeping yourself healthy.
