The present invention relates to the field of (vector) vaccines, and especially to novel promoter sequences, expression cassettes and vectors, which are suitable to express genes of interest, especially antigen encoding sequences. The viral vectors of the present invention are useful for producing an immunogenic composition or vaccine.

Embodiments of the instantly claimed inventions include, but are not limited to, chimeric viral constructs, non-human primate models, in vivo screening systems for antiviral agents, gene therapy delivery systems, and methods of making and using the same. In some embodiments, chimeric viral constructs include a non-human primate infecting virus nucleic acid sequence and a exclusively human pathogenic virus nucleic acid sequence for use in creating a non-human primate model and uses thereof. In other embodiments, systems for testing antiviral agents are disclosed. In other embodiments, gene therapy delivery systems disclosed herein can be used to deliver a vector containing or associated with an agent to a human subject for treating conditions of the skin and neuronal ganglia in the subject.
