Totally and completely off topic (hopefully the OP wouldn't mind a derail)
Sort of speaking of Yazbak...
...but does this sound right to you?

| In its July-August (2004) issue, the American College of Physicians’ Observer carried the following statement: “Influenza is the sixth leading cause of death for older Americans and infects 5% to 10% of elderly Americans every year. The flu leads to 300,000 hospitalizations and kills 30,000 to 40,000 Americans every year.” |
Now..if we go with the 10% figure...that would be catching the flu once every 10 years, right?
And if the flu vaccine is 30% effective in the years when the strains match...and the strains only match about half the time (and I think even that's being liberal...seems like it's more like one out of three years)...that gives you about a 15% chance of the flu vax working should you catch the flu.
How many years does someone need to get the flu vax before there's a liklihood that it'll be of benefit?
I'm horrible with math, but it seems like if you get the flu vax every year starting at birth and live to be 100, ONE of those years the flu vax might actually do something for you.
Is my math terribly off there?
