Here's an interesting piece of fact - not myths or hypothesis. A recent paper was published in a medical journal that discussed the effectiveness of flu vaccines after reviewing almost 6000 studies. Here's the main conclusion:
"A major review appeared in the journal Lancet Infectious Diseases (1) in October (principal author Prof. Michael Osterholm, a respected researcher into infectious diseases). The paper, which found only 31 studies worthy of inclusion out of a massive 5,700 screened, concluded that there was only good evidence for moderate flu vaccine efficacy in healthy adults, and no real evidence of protection in those over 65 years, or for that matter in children. Of course it is the elderly, and particularly the frail elderly, that doctors are more concerned about - and in whom 90% of flu cases occur - and there was no evidence that flu vaccine prevents flu infection in this group.
The pooled effect in those healthy adults, aged 18 to 65, is reported as 57%, which means the vaccine roughly halves your chances of getting flu. What is well known about placebo effects can account for most of that 57% effect. If you know you've had a shot for the flu you think you're invincible. But since the chance of getting flu in that age group was less than 3% to begin with, that's really only about a 11/2 percent reduction. Rounding the figures off, if you're a healthy adult, the flu vaccine will reduce your risk of actually getting the flu from 1 in 36 to 1 in 83. These are figures that are not offered in any of these studies.
Then of course, this all happens at a price. Whatever you may have heard, there is no such thing as a medication without the risk of side-effects."

So in other words NO ONE has been able to this date PROVE the flu vaccine reduces flu in children or the elderly - because it simply doesn't. This is just fact. Now it will reduce your risk in a healthy adult. A healthy adult has less than a 3% chance of catching the flu to begin with and it does reduce it to a 1.5% chance. But honestly, if you do a little research on how vaccines work, you realize they DO suppress the immune system temporarily and they only cover certain strands. So while your immune system is down, I would think that would increase your risk of getting sick with strands that aren't in the vaccine. But that's just my own logical conclusion. :)
I do know that at least one of the particularly nasty strands going around is NOT covered in the vaccine. I've had many friends getting the flu who have been vaccinated and they are all getting it just as bad if not worse than my nonvaccinated friends. Actually most of my nonvaccinated friends have not gotten as of yet. And though it certainly is not made well, known, if you dig a little, you'll find that some of the cases of children dying from the flu are children that were vaccinated. ;(
Here's a link showing one 14 year old that died despite being vaccinated - in August (so it wasn't like the 2 week thing everyone talks about.)

I'm not saying you shouldn't get a flu vaccine. That's an individual choice. I'm just saying that sometimes bad things happen and for many people the flu vaccine provides a false sense of security.
The best protection is common sense - stay away from heavily populated indoor areas as much as possible during epidemics. ALSO good health habits are a MUST. Vitamin D has actually been shown to do more for preventing the flu than the vaccine. Fresh air, exercise, healthy food, and hand washing are all major things that help prevent it, as well. And if you DO get sick, keep a close eye and get medical care.
