As it is, the flu is a nasty disease, and there have been pandemics in the past where large numbers of people have died. Now a mad scientist has made a flu that can bypass our immune systems. Aside from the question of “dear god, why would you ever want to do this?” (and I suspect that the answer is “For Science!“), now that we have this super-dangerous thing, how do we keep it safe and out of the hands of terrorists? I don’t have a good answer for this. The original version of this flu killed half a million people, and the new version would be much worse if it ever were released in the wild.
Actually, articles like one are easy to make sensationalist and sound like the world is ending. Actually, this kind of research into how viruses evolve helps researchers make better vaccines.
