The real effort to create such a virus is not clear, but I always wonder why governments never tried to make an effort in order to make humanity more resilient to attacks of this kind (natural or artificial) with education. The incredible thing about viruses is that if you have a disciplined population that stays home as much as possible, avoid contacts during interactions, and so forth, during an epidemic issue, you can do wonders at containing the event. But for some reason we are not prepared at all to act rationally to such an event.
