So a teammate that is turned into a vampire can't be reasoned with under any circumstance?

Not that they can't, it's just the infintesimate chance that you might get through to someone in the middle of the first hunger is so tiny that it's not worth it, and you ain't getting them to stay still long enough to get the SCU on. Vamps and wolves are just too dangerous to fuck with.
