Ad19a/64 Adenoviral Vector

Ad19a/64 vector for vaccination

Our proprietary Ad19a/64 vector (Subtype D) can be used to overcome the low transduction efficiency of commonly used Ad serotypes and help overcome the challenge of pre-existing immunity. It is an attractive alternative for the most commonly used human adenovirus type 5 (Ad5) for specific types of applications.

Ad19a/64 is the first accessible subtype D adenovirus vector. This vector provides superior transduction of human cells (e.g., dendritic cells, cardiomyocytes, fibroblasts, PBMCs, myoblasts, and myotubes) when compared to Ad5. It also possesses CAR-independent binding properties, targeting sialic acid-dependent receptors. In preclinical vaccine studies, the vector induced superior levels of CD4 and CD8 immune responses in non-human primates.
