Have they done an unbiased study (not funded by Pharma, the FDA, or CDC) on the number of casualties from the flu- vaccinated vs. non-vaccinated? Since they've practically sold out, er, run out of serum, they should have a good database of vaccinated participants vs the unvaccinated portion of the population. This should give us a good feel for it's effectiveness and whether or not it exarcerbated/worsened symptoms or caused death when it was introduced.
The problem is that with something like influenza, you;re shooting at a moving target.
A long, long time ago I used to be invloved - peripherally (sp:?) - with things like medical research into virususususes and cancer. As it was explained to me, specific classifications of viruses tend to mutate relatively rapidly, which is the reason why you can't eliminate the virus through vaccination. It is also the reason why the Influenza outbreak in the early 20th century was so deadly, and nowadays is no worse than the symptoms of looking at nekked pictures ot teedubbya.
This is in contrast to something like smallpox, whose genetic structure makes it less likely to mutate, and thereby making innoculations far more effective in nearly wiping out the bug.
It is also complicated by the fact that Influenza tends to only be widspread in colder, drier environments, and has less frequency in wetter, warmer climes (and no, I'm not talking about MAC's skivvies).
So when they make the vaccine, they have to guess what strains of the flu will actually pop up that year, which is part of the reason why it is only 60% effective. It doesn't cover recently mutated strains of the virus.
The vaccination uses dead virus, which is detected in the body by the immune system, tagged, and then destroyed. The immune system them generates "memory" cells for the virus that linger in the body for an extended period of time. However, a slight mutation of the virus can avoid being detected by "memory" componets of your immune system, attack, and replicate inside of vulnirable cell.
So, you see, any study has to take into account a *lot* of facotrs when it comes to the effectiveness of a vaccination for something like the flu.
