Development of a Novel Mucosal Vaccine Vector Derived From Human Parainfluenza Virus Type 2 and Its Efficacy as a SARS-CoV-2 Vaccine by Intratracheal Administration Using Transgenic Mice Expressing Human Angiotensin-Converting Enzyme 2
{{output}}
We created a novel replication-incompetent vector derived from the human parainfluenza virus type 2 (hPIV2). The vector lacks the hemagglutinin-neuraminidase (HN) gene (hPIV2/∆HN) that is essential for virus attachment and release. We also generated the stabl... ...
