A live vector vaccine is a vaccine that uses a chemically weakened virus to transport pieces of the HIV virus in order to stimulate an immune response.[1] A vaccine is an antigenic preparation used to establish immunity to a disease. ...

Live recombinant vectorvaccines are constructed by inserting HIV or SIV genes into live, infectious, but non-disease-causing viruses or bacteria such as vaccinia virus or Bacille Calmette-Guerin (BCG).
Recombinant viral vectors enter cells and allow the HIV or SIV proteins to be generated inside the cells; these proteins are then presented to the immune system in the same way that proteins from a virus-infected cell would be.
In addition, some livevectorvaccines may be capable of generating a mucosal immune response.
Attenuated vaccine: A vaccine in which live bacteria or viruses are weakened through chemical or physical processes in order to produce an immune response without causing the severe effects of the disease.
Vector: The organism, typically an insect, that transmits an infectious agent to its alternate host, typically a vertebrate; in human malaria, the vector of the parasite are mosquitoes, the "carriers" or "hosts" are humans.
In vaccine research, a bacterium or virus that does not cause disease in humans and is used in genetically engineered vaccines to transport genes coding for antigens into the body to induce an immune response.
