I felt a chill run down my spine. This was something I hadn't anticipated. My vaccine was designed to prevent infection, not cure it.
The old man looked at me expectantly. "Can you help them?"
The survivor, a grizzled old man, eyed me warily. "We've heard of your vaccine. It works, but it's not a cure-all. What about the people who are already infected?" I felt a chill run down my spine
As I left the building, I couldn't shake the feeling that I was running out of time. The zombies were getting smarter, and the survivors were getting desperate. I had to come up with something, and fast. The world depended on it.
I shook my head. "I don't know. I need to study this... see if I can come up with something." The old man looked at me expectantly
One of the other survivors, a young woman, spoke up. "They're... changing. Their bodies are... shifting. It's like they're becoming something else."
As I walked through the deserted streets, I noticed that the zombies were getting more and more aggressive. They were no longer just shambling along, but were actually moving with a purpose. It was as if they were being drawn to something. It works, but it's not a cure-all
"Hey, you're the vaccine guy, right?" one of them asked.
