Let us consider an antibody cell type C1 which is generated in Person P1 against Virus V1. (C1 is just an example cell type) We assume C1 cells work successfully against V1 in P1. Let us assume we extract enough number of C1 cells from P1 and inject C1 into another person P2 who is infected by exactly the same virus V1.

Now, I have a number of questions:

1. Do the injected C1 cells work fine against V1 in P2 too?

2. What conditions are required to be satisfied so that the injected C1 cells work fine against V1 in P2?

3. How is it possible that the C1 cells make any incompatibility or problems with ordinary body cells in P2?
