causality
[kôsal′itē]
a relationship between one phenomenon or event (A) and another (B) in which A precedes and causes B. The direction of influence and the nature of the effect are predictable and reproducible and may be empirically observed. Causality is difficult to prove. Some social scientists contend that it is impossible to prove a causal relationship.

I believe the point Sirius was making is that one can already be infected with a virus etc and not know it when the flu shot is administered....and/or the flu shot itself triggers the bodies defense systems and may make one more suceptible to another type of infection.
The incidence of the shot itself causing a patient to come down with the flu is extremely low.
I'm with Gerbil on this one. I've never gotten a flu shot and I've rarely if ever gotten the flu. I've had friends who have gotten the flu shot and gotten sick as a result. Whethor their sickness was a direct result of the vaccine itself or whethor it was the result of the vaccine overworking the bodies defense system and thus making it more susceptible to other illnesses I don't know. But in either case had the person not received the vaccine they wouldn't have gotten their sickness. Now it can also be argued that the vaccine prevented them from coming down with the flu that they were vaccinated against but were they better off because they came down with one illness instead of another?

What you are guaranteed is a dose of mercury, formaldehyde, antibiotics, squalene and other assorted neurotoxins and toxics directly into your bloodstream. No thanks.
The 2 people I know who got the flu shot this year both got ill for at least a week.
(Antibiotics are good things)
Also, logical fallacy, getting flu shot then getting sick does not mean causation.
I remember being a freshman in college and taking a class in logic. The fallacy you cite is called
post hoc ergo propter hoc(after therefore because).
Here's an example:
I drank a glass of milk for the first time in years and the next day I was sick. Therefore I conclude that drinking milk made me sick. Of course there may have been a bunch of other foods that you ate or fluids that you drank or you may have gone swimming in a lagoon or visited a hospital, etc.
