Secondary Objective: To assess the preliminary immunogenicity of a single dose of SAX201 in a Chinese adults aged 18 years and older. Exploratory Objectives: 1. To evaluate post-vaccination viral shedding and genetic stability of the vaccine virus. 2. To assess the infectivity of the vaccine virus after vaccination. 3. To evaluate the risk of environmental shedding of the vaccine virus during and/or after vaccination. 4. To assess the potential risk of transmission of the vaccine virus to close contacts and/or pets resulting in clinical symptoms. 5. To explore the impact of pre-existing antibodies to the parainfluenza virus type 5 (PIV5) vector on vaccine immunogenicity.
