you can have an many flu jabs as you like, there is currently no vaccine for this H5N1 variant of influenza (but they're working on it).. thats why health organisations are getting worried..... what they're doing is stocking up on untested (against this variant ) anti viral drugs, so that if you do get ill, they can then hopefully treat you. The death rate so far had been about 50% where outbreaks have occurred. i'd be more inclined to learn how to wash my hands properly, remember the virus has to have a route into you..... and washing your hands properly will significantly reduce the risk, as far as i know its not an air borne disease, but cant be transmitted in aerosol form....sneeze/cough droplets.
