If you go back to Vault 22 and read the computer records, you will note that almost everything we learn about Vault 22 is what Keely (the ghoul researcher for the NCR you run into) has concluded. Keep in mind she only has been in the vault a few weeks (at most) before you get there. She's the one who talks about deaths and everyone dying, but what she actually is reporting on is where she found the bodies and what she thinks happened. Most of the computers in Vault 22 that don't have Keely notes just have door unlocks and the such - there are only a few relating to the actual original inhabitants and what happened to them, and those are all about things as they happen. So there is nothing that precludes the idea that some people fled the vault and ended up going north. Remember, Mr. House's efforts didn't eliminate all the nukes headed for the Mojave, just most of them. So leaving the area would make sense. And as Salerene notes, there is a cave you can use to get into Vault 22 from the other side anyway.
