It has to be the exact virus or it’s irrelevant, and it kind of can’t be done.

The virus has to get to the brain and spread around and “infect” cells in order to edit the DNA. It’s why it had trillions of the virus. It needs a slow and unprepared immune response so it can do the editing.

If they did a small dose test, you just vaccinated her against the virus. Her immune system would more quickly go after and destroy the virus. They expected her to get sick. They didn’t expect it to get that bad. She needed more powerful immunosuppressants beforehand.
