Did you just base your assumption that some science is dumb off of what happened in The Stand? A work of fiction? A work that seems to think that a fast-spreading virus is the most lethal kind of virus?
Since I wouldn't presume to think you'd gather anything from real research, take a gander at
The Hot Zone. Assuming it doesn't make your miniscule intellect implode under the weight of your ignorance and arrogance, come back and we'll talk.
Otherwise don't presume to think you understand the logic (or as you appear to believe, assuming you understand the concept of logic at all) behind epidemiology and infectious disease research. I do, and I can tell you know a dozen good reasons why recontructing the original 1918 flu can be beneficial:
By understanding the 1. transmission rate 2. environmental persistance 3. resevoir number 4. exact biochemistry and 5. relationship to current flu strains (both 6. historically and 7. genotypically), scientists (not Steven King) can predict future patterns of 8. influenza evolution 9. inter-species jumps, 10. regions of greatest outbreak risk, 11. pattern of spread using historical precendents and 12. vaccine strategies that may be most effective.
And that's just shit I thought of off the top of my head. Now think what researchers who do this for a living know, and consider how their reasoning and tactics are even better than mine.
