There is a theory about flu: Every ten years or so, a new virus will overcome 
the established ones. When a sufficient part of the population has been in 
contact with the virus,  life long vaccination effect forbid the illness 
return. When  the vaccinated people die of old age, the ground is free for 
the virus and a new pandemic can start.

 We are now more than 80 years after the Spanish flu  story, so it would be 
time to the virus to start again. I think there is a "good" probability that 
SARS is  a come back of Spanish flu, a flu-like virus with new antigenic 
properties. If it is that, we are going for nearly one billion deaths.
