Primary | Immunoglobulin G (IgG) anti-S antibodies | measured using the Elecsys® Anti-SARS-CoV-2 S assay (Roche, Rotkreuz, Switzerland) | At 3 weeks after the first-dose vaccination (T1) | |
Primary | Immunoglobulin G (IgG) anti-S antibodies | measured using the Elecsys® Anti-SARS-CoV-2 S assay (Roche, Rotkreuz, Switzerland) | At 3 weeks after the second-dose vaccination (T2) | |
Primary | Neutralizing antibodies | Reduction in plaque count of 50% (PRNT50) was calculated for the median neutralizing titer (ND50) using the Spearman-Karber formula | At 3 weeks after the first-dose vaccination (T1) | |

Primary | IL-6, TNF-a, and IL-1ß | measured by flexible customized bead-based multiplex panels for Luminex assays (Human Premixed Multi-Analyte Kit, R&D Systems Inc., Minneapolis, MN, USA). | At 3 days after the first dose | |

Primary | reactogenicity after vaccination | Local erythema/swelling was regarded as positive sign if larger than 2.5 cm in diameter. Systemic adverse events were graded as follows: grade 0, no systemic adverse event; grade 1, any adverse event that did not interfere with activity; grade 2, any adverse event that interfered with daily activity. Fever was classified as grade 1 (from 37.5? to 38.4?) and grade 2 (>38.5?). Systemic adverse events were classified into two ways: (i) the highest level of severity of any adverse event reported by the participants and (ii) with or without specific adverse event. | Until post-vaccination day 7 | |
Secondary | The correlation between humoral immune response and reactogenicity after vaccination | The correlation between humoral immune response and reactogenicity after vaccination | The correlation between reactogenicity after the first dose and immunogenicity at T1 (3 weeks after dose 1 prior to dose 2) and T2 (3 weeks after dose 2);the correlation between reactogenicity after vaccine dose 2 and immunogenicity at T2 | |
Secondary | The correlation between cytokine response and reactogenicity after vaccination | The correlation between cytokine response and reactogenicity after vaccination | At 3 days after each dose | |
Secondary | Long-term immunogenicity: Immunoglobulin G (IgG) anti-S antibodies | measured using the Elecsys® Anti-SARS-CoV-2 S assay (Roche, Rotkreuz, Switzerland) | At 3 months after the second vaccination (T3) |
