Arms & Interventions
Step 1: Placebo
Healthy adults and elderly subjects will be randomized to receive intramuscular injection of placebo.
Intervention: Placebo (Biological)
Step 2: Placebo
Healthy adults and elderly subjects will be randomized to receive intramuscular injection of placebo.
Intervention: Placebo (Biological)
Step 2: VN-0200 low dose
Healthy elderly subjects will be randomized to receive intramuscular injection of low dose of VAGA-9001a adjuvanted with low dose of MABH-9002b.
Intervention: VN-0200 (Biological)
