Most deaths from flu epidemics came from secondary infection. The flu has become a political and distribution problem like food.
There are some very promising vaccines in the pipeline (including end of Phase 2 or in Phase 3) that protect well against even flu strains not specifically targeted. The risk is that, before the new generation of vaccines come out, an epidemic occurs and affects poor nations without adequate distribution of antibiotics. I know that is not what you generally hear, but it is where we are currently at.
