In my (educated) opinion, flu shots are for the most part no more effective than a placebo.
You see, the problem is two-fold. First, the makers of the seasonal flu shots have to attempt to predict the strain(s) of the flu that are going to erupt as the season's problematic variants. This is at very best a crap-shoot. Think of this as a really bad version of meteorology.
The second inherent problem is that strains of the flu are very plastic - that is, their 'makeup' is highly subject to change/modification. Viruses and bacteria are (generally) adept at 'communicating' their genetic blueprints and swap identities readily. This is problematic when you design a flu shot since you are sort-of posting 'wanted' photos of pathogens that you anticipate being problematic. The flu has the impressive ability to change its identity very readily whilst maintaining its virulence.
So, considering the two aforementioned points, I see no current advantage to deliberately exposing myself to the flu shot.
