Scientists Rebuild the Spanish Flu Virus!!!
You can read about this debacle here
Personally, all I can think is "Didn't they learn anything from movies like 12 Monkeys and I Am Legend?" It isn't worth it!!! Don't recreate any viruses that killed millions of people just to study them! And don't use the excuse that 'Most people are immune to it now, so it couldn't become another epidemic' Yeah, right! Anyone who has watched any amount of science fiction knows that viruses morph and become more dangerous. With all the horror in the world, we really don't need another plague. Just my opinion.
