Preclinical Safety Evaluation of a Replication-Defective Canine Adenovirus Type 2 Vector-Based SARS-CoV-2 Vaccine Candidate in Murine Models
Background: Adenoviral vectors are widely used in vaccine development; however, pre-existing immunity to common human adenovirus serotypes can limit their effectiveness. Canine adenovirus type 2 (CAV-2) is a non-human adenovirus with low seroprevalence in humans, making it a suitable alternative vector. Despite its pro...
