Misleading
Assuming, for the sake of polite argument, that the numbers cited are valid and that the 300 days referenced means, more or less, the past 300 days, it strikes me that the poster is still a Big Lie. The clear implication is that all of these causes of death are comparable, dead is dead, after all, and H1N1 is a percent of a percent of the total and can/should/must be ignored. However, the causes listed are not comparable. There is a vaccine for H1N1; for most of the other causes listed, not. Nor was there a vigorous public debate six months ago about whether to spend the money developing an H1N1 vaccine or one for cancer or transportation accidents or war, because even stupid people aren't that stupid. The question was whether there was some likelihood of a worst case involving this particular virus that would justify the expense and effort of developing a vaccine, and the answer was yes. Whether the deciding point was a fair likelihood of a fairly bad worst case, or a small likelihood of a much worse case, or a much smaller likelihood of a national disaster I don't know or, much, care. Logically, the decision would make sense across a range of those possibilities.
I suspect that there are people who would only accept the need for the effort if the outcome is a worst case, but for that to happen the effort would have to have failed.
With regard to the poster, the H1N1 figures given are so far. Clearly we are supposed to extrapolate these figures into the future, which probably works fine for highway deaths, but not so much for a virus. Past performance is no guarantee of future results. In addition, there is no date given for the data. (I'll ignore the lack of sources since I said we could accept the data as valid for the sake of argument.) There is no indication that the data should be or could be updated, nor how someone might find an update. So, even if the figures were perfectly accurate when the poster went to press and even if they are reasonably accurate today, they'll be a tad off when they're still circulating in 2017 or whenever the next swine flu hits. They'll also be a bit misleading a month or a year from now in a worst case, the worst case being that H1N1 takes off in a largely un-vaccinated population -- with some still slow to accept the danger because they're invested in the 300-days story.
To be reasonable, the worst case seems somewhat unlikely, given that H1N1 first appeared in my area (Memphis, TN) six months ago and has chugged along steadily and almost unremarkably since. Those I've known personally (who have been diagnosed by physicians; I discount self-diagnoses) haven't been terribly ill, almost all far less sick than I would expect from seasonal flu. In addition, devastating world-wide epidemics are just not the most likely outcome of any disease.
So am I going to get the vaccine now that it's finally available here? You betcha! This is something that might be very, very bad. Even if it isn't, in the best case flu is thoroughly unpleasant and I can easily, cheaply, and safely protect my family from it. Explain to me again why I shouldn't do that.
