Dr. Tsing says that each delinquent will give them 8 doses. That means they had the opportunity to "cure" at least 40 MM. They also harvested from Monty and Harper, just not to death, so you could add on at most 7 extractions from each (+14 total). It takes 48 hours before the marrow works, so the extractions from Fox and the other delinquent at the very end wouldn't have taken effect before Clarke irradiated Mount Weather (-16). Dr. Tsing most likely had been given the marrow but it just didn't have time to take effect before she was exposed.

There were several other MM immune: the guards who went into Level 5 to take out the Delinquents, the guards up on the ridge above the door, and the guards who captured Abby, Kane, Miller's Dad, and Monroe. They all died during these events until Emerson, Dante, and Cage were the only ones left in the Mountain who were immune.

Jason Rothenberg has also confirmed that Emerson is the only survivor of Mount Weather.
