Safe and effective poxvirus vectors--NYVAC and ALVAC

Abstract

This paper describes the development and in vitro/in vivo characterization of two highly attenuated recombinant poxvirus vectors. The vectors, NYVAC and ALVAC, exhibit a restricted host range and a greatly enhanced degree of attenuation following inoculation into a range of animal species by a variety of routes. The safety profile of these vectors, together with their demonstrated ability to induce both humoral and cell-mediated immune responses to extrinsic antigens, makes them ideal candidates for use as vaccines in both human and veterinary disease situations.
