Outcome Measures
Primary Outcome Measures
- Adverse Event (AE) [30 minutes after vaccination]
Observe the AEs occurs at different time point after vaccination
- AEs [0-7 days after vaccination]
Observe the AEs occurs at different time point after vaccination
- AEs [0-28 days after vaccination]
Observe the AEs occurs at different time point after vaccination
- Serious adverse event (SAE) and adverse event of special interest (AESI) [Within 12 months after vaccination]
Observe the SAE and AESI after vaccination
- Neutralizing antibody geometric mean titer (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

Neutralizing antibody GMT of Delta variant and Omicron variants (BA.2, BA.4, BA.5)
- Neutralizing antibody titer of other SARS-CoV-2 variants (MRNT) [Until 12 months after vaccination]
Neutralizing antibody titer of Delta variant and Omicron variants (BA.2, BA.4, BA.5) by MRNT
- Neutralizing antibody titer of other SARS-CoV-2 variants (SVNT) [Until 12 months after vaccination]
Neutralizing antibody titer of Delta variant and Omicron variants (BA.2, BA.4, BA.5) by SVNT
- Anti-SARS-CoV-2 receptor-binding domain (RBD) antibody level [Until 12 months after vaccination]
Anti-SARS-CoV-2 RBD antibody level after vaccination
