Hell, what if we can't developed new vaccines because the virus has become so evolved? Because the virus is so resistant to drugs?

End game. We're dead. That could actually happen if viruses outpace technology. Ergo why doctors usually beg people not to use antibiotics on common colds and the like.

Vaccines on the other hand should be mass distributed. The more people become immunized, the less victims a virus has. The less victims a virus has, the lower the chance random mutations will occur, and thus, the less likely new viruses will be created from the old design.

We just about eliminated smallpox and measles in this manner. We left them so few carriers they couldn't spread, effectively rendering them dead... Until the anti-vaccine movement came along... Yay...
