Obviously a fever, in the case of an attenuated and not inactivated vaccine, can be easily linked causally. Reactive arthritis becomes harder, because what you're essentially saying it "the flu antigens caused a immune reaction that targeted the joints" as in if you would have gotten the flu you would have gotten a reactive arthritis anyway because that is how you reacted to the flu shot, which has flu in it. On top of that other viruses could have infected you in the mean time and caused it.
The problem is that you see a vaccine as something entirely different from the virus. It isn't. It is just virus particles which cause all the disease you mentioned. Flu as a complication has.... reactive arthritis! As do many other diseases. You wanna know how many hundreds of babies I have seen who got the sniffles and then parents show up in a panic because they won't use one leg?
Quick x-ray to be sure. No fever. It still laughs and plays with my stethoscope. Go home, it'll be fine in a week.
Guillian barre can also happen from the flu! So again why I said 5 in millions isn't odd is because it isn't HIGHER than the normal rate we see reactive arthritis and Guillian Barre FROM normal respiratory infections SUCH AS THE FLU.
Like I said, always read side effects. If these are UNACCEPTABLE to you DO NOT USE A MEDICATION. However flu vaccines (and again depends on which type and batch) show a far lower incidence of adverse events than just getting the flu.
