No seriously, I don't see the application of the vaccine as much of a problem (since apparently it's pretty fucking easy even for an organization as incompetent as the fireflies to cross the country even with the military hunting them) as dealing with the infected because you would need to eradicate every single last one of them, since apparently they won't die on their own, as evidenced by there still being masses of infected after two entire decades and god knows how many firebombings.
At least the original Living Dead had cosmic rays, but this shit doesn't even follow its own internal logic.
