Anti-virus

In the continuity of the films, the Anti-Virus is the only compound capable of purging the T-Virus. It was created by Dr. Charles Ashford as a means to help his daughter, Angela Ashford, retain her mobility.

It was distinguished from the T-Virus by being green in color, in it's liquid state.

The Anti-Virus is not fool-proof, however. Rain Ocampo, who had been bitten several times and spent more than an hour in an infected state, died and reanimated as a zombie a few minutes after being administered the antivirus. Dr. Sam Isaacs was bitten and infected by an enhanced zombie; several massive doses of the Anti-Virus could not save him from extensive mutation.
