Outcome Measures

Primary Outcome Measures

  1. Neutralizing antibody GMT of Omicron BA.5 [28 days after vaccination]

    Neutralizing antibody GMT of the most prevalent SARS-CoV-2 variant (Omicron BA.5)

Secondary Outcome Measures

  1. Neutralizing antibody GMT of other SARS-CoV-2 variants [7 days, 14 days, 28 days, 3 months, 6 months and 12 months after vaccination]

    Neutralizing antibody GMT of Delta variant and Omicron variants (BA.2, BA.4, BA.5)

  2. Neutralizing antibody titer of other SARS-CoV-2 variants (MRNT) [7 days, 14 days, 28 days, 3 months, 6 months and 12 months after vaccination]

    Neutralizing antibody titer of Delta variant and Omicron variants (BA.2, BA.4, BA.5) by MRNT

  3. Neutralizing antibody titer of other SARS-CoV-2 variants (SVNT) [7 days, 14 days, 28 days, 3 months, 6 months and 12 months after vaccination]

    Neutralizing antibody titer of Delta variant and Omicron variants (BA.2, BA.4, BA.5) by SVNT

  4. Total IgG antibody level [7 days, 14 days, 28 days, 3 months, 6 months and 12 months after vaccination]

    Total IgG antibody level of SARS-CoV-2

  5. Spike protein antibody level [7 days, 14 days, 28 days, 3 months, 6 months and 12 months after vaccination]

    Antibody level of anti-SARS-CoV-2 spike protein

  6. RBD antibody level [7 days, 14 days, 28 days, 3 months, 6 months and 12 months after vaccination]

    Anti-SARS-CoV-2 RBD antibody level

  7. Specific cytokine secretion levels [7 days, 14 days, 28 days, 3 months, 6 months and 12 months after vaccination]

    Specific cytokine secretion levels such as IFN-γ

  8. AEs [30 minutes, 0-7 days, 0-28 days after vaccination]

    Observe the AEs occurs at different time point after vaccination

  9. SAE and AESI [Within 12 months after vaccination]

    Observe the SAE and AESI after vaccination
