provision = preparation?

Context:

Whilst treatment was not a primary focus, the concurrent
problem of balanced management of infection and autoimmunity
was continually annotated during the meeting. Definitive treat-
ment requires provision of ‘intact’ hemopoietic tissue by bone
marrow transplantation from a compatible donor, which ameliorates infectious and autoimmune expressions but confers the hazard of graft-versus-host disease. Gene therapy is a future option.
