Yes, so far several veterinary but no human DNA vaccines have been approved for use (see below from).
Approved Prophylactic Veterinary DNA Vaccines
West Nile Innovator® againstvirus in Horses. The US USDA approved this vaccine in 2005. Contains two genes encoding West Nile virus proteins ( ).
Apex-IHN® against( ) disease in farm-raised Atlantic Salmon. Consists of a plasmid containing a virus glycoprotein gene ( ).
Approved Therapeutic Veterinary DNA Vaccine
Oncept™ against Oral Malignant Melanoma in Dogs. This vaccine encodes human tyrosinase. Rationale is it would drive cross-reactive cytotoxic T cell responses against dog tyrosinase highly expressed by melanomas (). Cross-reactive in this context means once activated by this DNA vaccine, dog T cells specific for peptides derived from human tyrosinase would then respond to similar peptides derived from dog tyrosinase. Keep in mind, this isn’t a stand-alone DNA vaccine effective against a tumor all by itself. It’s only been shown to be effective as an adjunct to surgery for oral malignant melanoma in dogs, i.e., when done after primary tumor’s been surgically removed.
Approved Gene Therapy Veterinary DNA Vaccine
DNA plasmid that expresses the natural form of the(GHRH). When given to reproductive age sows, it reduces fetal ill-health and deaths, and thus increases number of surviving babies per litter (5, ).
