On flu

With news reports saying that this year's flu season will be even worst than the last, I can actually see myself turning into a young, female version of Howard Hughes.
You see, I hate being sick. Yes, I love time off work (doesn't every body?) but it's hardly ever worth it when you feel so bad. You can't even enjoy the best things in life - like eating, reading, or tv - properly because you just feel so awful. On the upside, sleeping becomes a hobby, or even a sport.
I'm giving serious thought to public transport during this Autumn/Winter and am considering paying for parking in the city just to avoid it. I just don't want to be somewhere where people sneeze into their hands then put them on a pole, or a handhold. Or cough on all the people within a 2m radius. I don't know about you, but hearing one of those hacking, chesty coughs that sound like bronchitis immediately make me feel sickly.
And yet, I haven't seriously considered getting a flu needle. There are apparently two types of vaccination this year - one for swine flu, and one for the latest strain of influenza. My mum gets them every year, but she's a teacher and you know kids; walking virus factories...
If anyone has an opinion, I'm interested. Should I get the vaccination? Or rely on natural immunity to get me through the flu season?
