There is no "flu". It's many different viruses with different outcomes. So unless you know you got the exact same strain as someone else you can't
compare your recoveries. Even then there are many factors that determine outcomes, so attributing anything to the vaccine just isn't possible for you
to do.
likely it has been said but i have not gotton the flu either so why on earth would anyone believe i would be ok with them putting last yrs flu into a
needle and shooting me up.
