At the risk of almost repeating a question I asked some time ago...
Scenario: A character has been cured of a deadly disease, but all records of the cure have been destroyed (files, actual meds, etc). Now the character is facing the decision of staying in a place of safety, or leaving this place in order to share the information of the cure with others.
My question is: Is this a false dilemma? Is there a situation in which the person would be needed in order to "reverse engineer" a cure, or would a simple blood sample be sufficient? I'm trying to work up a dramatic plot moment, but I don't have the medical knowledge to know if this is realistic. Appreciate any feedback!
Edit: I should add that the character is able to freeze a blood or tissue sample if necessary. So, yeah. I just made it even harder to make this dramatic plot twist. My foot hurts from shooting it, but what can ya do???
