Applications of canarypox (ALVAC) vectors in human and veterinary vaccination

This paper presents data derived from safety and efficacy studies of ALVAC-based rabies and feline leukemia virus (FeLV) vaccine candidates in target species. Inoculation of the ALVAC-RG recombinant was well tolerated in all species including humans and very young dogs. Protection induced in dogs against rabies challenge was long-lasting and could be elicited in the face of high levels of maternally-derived neutralizing antibody. Parenteral inoculation of cats with an ALVAC-FeLV recombinant was safe and induced protection against persistent infection following oro-nasal FeLV challenge.
