Sarah-I said:
I don't quite understand why someone who is young, fit, healthy and with a good immune system would want to bother having a flu vaccination? I can understand the very young, the very old and those with chronic diseases having vaccinations and I can see the point in this very much.
The way I look at it is that I am still young, fit and healthy, so by not having a flu vaccine, there is more for those that really need it. The last time I had a proper dose of flu was about 30 years ago. No kidding either. Yes, I have had bad colds in between, but not flu.
Surely, if you have a good immune system and are young, fit, active and healthy, then you don't need a flu jab.
I won't be having one!! 
Well, that's very noble, but perhaps rather silly too. Soldiers don't head into battle naked these days - they wear all the armour they can reasonably carry, and for very good reason. Certainly you may think you are more likely to be able to withstand the effects of flu if you are young and healthy, but it is no picnic at any age, as Eos has pointed out.
Consider, for example, your own susceptibility to the virus. You may be one of those unfortunate people for whom, despite their youth and vigour, the flu virus is an awful or even tragic experience. You may get hospitalised, for all you know. Sure, last year's strain of the flu virus may have been shaken off with a lemon-and-honey tea, but this year's may be much more devastating. And even just running the course of a flu infection probably means you are off work - you suffer, your work suffers - it costs money to be sick, and not just to pay the medical bills.
Or if you battle on and turn up in the workplace while sick, you may easily pass the flu virus on to more susceptible people there, including elderly people and possibly even pregnant women. If not protected, their sicknesses can greatly affect work productivity, not to mention their personal discomfort and expenses.
Sarah, you said you are a medical practioner of some sort, a person who personally examines lots of different people daily, young and old, in close proximity. You having the flu in such a position would be unnecessarily exposing those people who are already sick to the likelihood of additional debilitating illness. Do you think that's an ethical thing to do?
So remember, the flu vaccine significantly reduces the risks of these things happening.
If it makes any difference, I won't be having a flu vaccine either, but not because I don't want it. Simply, I am allergic to the medium on which they make the vaccine, and I would go into shock if I was injected with it. Otherwise I would be lining up too. As it is, I have to suffer through the winter season being VERY careful not to get near flu-carriers...like you might be.
