(1) Somatic cell gene therapy. A cloned gene can be "packaged" in a harmless virus (vector) and then inserted into the nuclei of cultured stem cells from the patient with a deficient gene: then the "engineered" cells are then injected back into the patient, where the added gene will restore normal function

(2) Viruses can prevent an immune response in sending helper T cells, cytotoxic T cells, memory B cells to antigens thus causing the onset of secondary infections
1. In nature they can cause mutations to the genetic material when they reproduce. That is how some viruses cause cancer. 2. Viruses can also be used in gene therapy.
