'The Walking Dead's Robert Kirkman On "Biter Immunity"

Robert Kirkman, last season show runner on The Walking Dead, was asked if anyone "had immunity" during a panel discussion on the Walker Stalker Cruise "No, that would be terrible," Kirkman said. "That's not a storyline I like."

Could show writers put the idea of a character being immune to bites out into the Walking Dead universe? Maybe. Still, Kirkman doesn't seem anxious to actually make someone immune, at least for the time being, for several reasons.
