I'm working on fleshing out a random plot idea that keeps knocking on my door, but I've run into problem and would appreciate other peoples' input. I was thinking along the lines of a government engineered virus getting released by accident and the vaccine or cure first raising mortality and then "helping" the virus mutate. That's where my problem starts. It'd be all to easy to introduce zombies at this point, but it's too little, too late for zombie fans and probably too much for "haters". Being a fan myself, I can't judge the reception of the latter, so, I'm asking for opinions: Go undead or come up with a different final ~3rd? If it matters, I don't intent to go commercial with this, just sites like fictionpress if at all.
