has anyone thought that since Tanya is "immune" that she figured out a drug cocktail to stop the transformation? She did say she "studied" several people in various stages of infection, WHICH would mean she used a variety of drug combos to see what will slow/stop/kill the infection!

I would also think she used herself as a guinea pig when she was bit and also used it on Saul after his injury to insure his protection against the infection...


Anyone think this is the most likely of the scenarios?
