结局指标
主要结局

Proportion of unsolicited AEs within 28 days post dose injection. Unsolicited AEs are all other adverse events (those that do not fall under the categories of solicited AEs).
Proportion of solicited local and systemic AE
时间窗: Within 7 days (Days 0 - 6) post dose injection
Proportion of solicited local and systemic AEs within 7 days post dose injection. Local AEs at the site of injection: Pain, tenderness, erythema/redness, swelling/induration, pruritis. Systemic AEs: Fever, fatigue/general weakness, chill, headache, myalgia, arthralgia, diarrhea, nausea/vomiting, abdominal pain, mucocutaneous reaction/rash, urticaria, dizziness, cough, dyspnea.

Proportion of Adverse Event Of Special Interest (AESI)
时间窗: Throughout the study duration, 12 months post dose injection
Proportion of any AESI from the administration throughout the entire study. AESI are categorized into 1) AESIs included because they are seen with COVID-19 Disease, 2) AESI included because they have a proven or theoretical association with immunization in general, 3) AESI included because they have a proven or theoretical association with specific vaccine platform(s).
