Brief Summary:
This is a phase I, open-label, dose-escalation clinical study to evaluate the safety, tolerability and immunogenicity of 3 ascending doses of UB-612 COVID-19 vaccine in healthy adults, aged from 20 to 55 years old.

Condition or disease Intervention/treatment Phase
COVID-19 Biological: UB-612 Phase 1

Detailed Description:
This is a phase I, open-label, dose-escalation clinical study to evaluate the safety, tolerability and immunogenicity of 3 ascending doses of UB-612 COVID-19 vaccine in healthy adults. Up to 60 subjects (20 subjects per group) will be enrolled into this study. Subjects in each group will be enrolled to receive two doses of UB-612 vaccine at 28-day interval (Day 0 and Day 28).

Arm Intervention/treatment
Experimental: Group A (Low dose)
20 subjects will be enrolled to receive low dose of UB-612 vaccine.
 Biological: UB-612
UB-612 is a proprietary high-precision designer S1-RBD-protein based vaccine incorporating a Th/CTL epitope peptide pool which could bind to human MHC-I and MHC-II to activate T cells.
Experimental: Group B (Medium dose)
20 subjects will be enrolled to receive medium dose of UB-612 vaccine.
 Biological: UB-612
UB-612 is a proprietary high-precision designer S1-RBD-protein based vaccine incorporating a Th/CTL epitope peptide pool which could bind to human MHC-I and MHC-II to activate T cells.
Experimental: Group C (High dose)
20 subjects will be enrolled to receive high dose of UB-612 vaccine.
 Biological: UB-612
UB-612 is a proprietary high-precision designer S1-RBD-protein based vaccine incorporating a Th/CTL epitope peptide pool which could bind to human MHC-I and MHC-II to activate T cells.
