An adenoviral vector is a genetically engineered, replication-deficient adenovirus used as a delivery vehicle to introduce foreign genetic material into target cells. It retains the virus's natural ability to efficiently infect a wide range of dividing and non-dividing cells without integrating into the host genome. It is widely used in gene therapy, vaccine development, and cancer treatment research due to its high transduction efficiency, large genetic cargo capacity, and well-characterized biology.
