You make some good points in the OP. (S and F.)
I never go for flu vaccines.
What I do notice some times, is that people that do go for the flu vaccines, often end up getting the flu anyway, while at the same time, I don't get the flu.
I have seen this enough times, so that I do not believe in going for flu vaccines.
