This research is getting less press than one would expect given the hysteria over the Flu (and I'm not even talking about Avian Flu). Many people pin their hopes on the flu vaccine which is based on the previous year's virus. It is next to worthless unless you're a hermit and never interact with people who have been sick with the flu the year before, in which case it's totally worthless, because, well, you're a hermit. See here:
Each vaccine contains three influenza viruses-one A (H3N2) virus, one A (H1N1) virus, and one B virus. The viruses in the vaccine change each year based on international surveillance and scientists' estimations about which types and strains of viruses will circulate in a given year.
I love estimations. They're so like, totally accurate, ya know? Just like all those hurricanes we've had in 2006 that were estimated by scientists.
With the amount of money, pr, fear, and energy invested in the flu vaccine, one would investigate, thoroughly, the benefits, right? Right.
