The flu shot is called a shot because it isn't one vaccine, it's multiple at once.
The low efficacy is, at least in part, because every spring they make an educated guess as to which ones would be best to put into the shot distributed in the fall. Not all of them can be put into the shot for cost and compatibility reasons.
