Unfortunately, the flu shot won't protect you from other flu/cold respirtory virusus (and there are hundreds of them) ...they can only predict which three will be the most deadly and put them in a shot...but, they can be off a bit.
It's easy to get many coldin succession if you've been exposed to them and your immune system is run down.
You could consider to take something like Cold FX, Zicam (in the US), Mucinex (in the US), up your zinc a bit..etc.
I was sick last year from fall to the end of Feb three times. It sucked big time...I can relate to how you feel.
Tonight, I just started to get a slight tickling in my throat with a bit of a cough to relieve it.....I hope I'm not getting sick...aaargh!!! I haven't been all summer/fall/winter ....soooo, I've taken double zinc, Cold FX, echinacea, vitamins, carrot juice, double my asthma preventor inhaler and a zantac just in case it's reflux...lol!
I hope you fight it off...for I do hate getting colds. As far as the flu...I've had it a few times in my life...horrific!
