Respiratory Syncytial Virus (RSV) Vaccines Based on Promoter-Proximate Attenuation
Available for licensing and commercial development is a patent estate and related biological materials for producing therapeutic or prophylactic vaccines against Respiratory Syncytial Virus (RSV). The claimed vaccine strategy relates to the engineering and creation of live-attenuated RSV vaccine candidates by shifting the position of one or more viral genes relative to the viral promoter (aka promoter-proximal attenuation). The gene shifts can be constructed by insertion, deletion or rearrangement of genes or genome segments within the recombinant genome or antigenome.
