You really need to get your facts straight.

First off, Frank got out of Willamette. The ending said as much. He manages to get his story done and reported the incident to the public, forcing the government to take responsibility.

Secondly, Isabela is able to make a zombrex-esque medication for preventing the zombification process. Who's to say she didn't continue to do so for Frank until Zombrex was created. And we don't even knew when Zombrex was created in the first place.
