Nonintegrating lentivector vaccines stimulate prolonged T-cell and antibody responses and are effective in tumor therapy.

Lentiviral vectors (lentivectors) are effective for stimulation of cell-mediated and humoral immunity following subcutaneous and intramuscular immunization. However, lentivector genome integration carries a risk of perturbation of host gene expression. Here, we demonstrate that lentivectors with multiple mutations that prevent integration are also effective… (More)
