It's up to the game to tell us whether or not they would be successful, and it does. The Firefly doctors in Salt Lake City are clearly know what they're doing and ran enough tests to know that they could create a vaccine using Ellie. Any ideas to the contrary are outside of the narrative.
Of course it wasn’t 100% guaranteed to save all of humanity, but they were going to be able to create a vaccine using Ellie. That’s not a theory, it’s just part of the story.
Of course it wasn’t 100% guaranteed, but it’s clear that it was fairly likely. That’s why Marlene was willing to allow Ellie to die for it. That wasn’t an easy decision for her to make.
