What stops us from inducing a CCR5 delta 32 mutation in hiv infected people?

What process do we have to reliably mutate every single cell of certain types in bone marrow, with only a desired mutation and no other?
a modified HIV vector?

DNA Vaccines?
We don't have a process to do what is described.
That's not accurate. If that were the case, then ANY bone marrow transplant could potentially cure an HIV patient. What's happening is that bone marrow is what generates white blood cells, and the donor in this case was naturally resistant to HIV due to the CCR5 delta 32 mutation. This results in white blood cells that HIV can no longer easily enter.
So what's happening is ALL of the patient's white blood cells are being replaced (rather, generated by this new donor marrow) with ones that are resistant to HIV.
