The geometric mean concentration (GMC) of anti-gE antibodies one month after full vaccination. Timeframe: At Month 0 and Month 3. Anti-gE antibody concentrations, were determined by ELISA, expressed as Geometric Mean Concentrations (GMCs), in milli international units per milliliter. ### Secondary outcomes 1. The seroconversion rate of anti-gE antibodies one month after full vaccination. Timeframe: At Month 3. Vaccine response was defined as: For initially seronegative subjects, antibody concentration at post-vaccination ≥ 4 fold the cut-off for Anti-gE; For initially seropositive subjects, antibody concentration at post-vaccination ≥ 4 fold the pre-vaccination antibody concentration. 2. The incidence, severity, and vaccine-related association of solicited local adverse events (AEs) within 7 days after each dose of vaccination. Timeframe: During the 7 days (Days 0-6) after each vaccine dose. This typically refers to the documentation and assessment of local adverse events (such as pain and swelling at the injection site) that occur within 7 days after vaccination in clinical studies or vaccination programs. This includes the frequency of occurrence, severity (usually categorized as mild, moderate, and severe), and the investigator's assessment of the association between these events and vaccination. 3. The incidence, severity, and relevance to vaccination of solicited general adverse events (AEs) within 7 days after each dose of vaccination. Timeframe: During the 7 days (Days 0-6) after each vaccine dose. This typically refers to the documentation and assessment of general adverse events that occur within the 7-day observation period after each vaccination dose, including the frequency of occurrence, severity (such as mild, moderate, and severe), and the investigator's assessment of the association between these events and the vaccination. 4. The incidence, severity, and relevance to vaccination of unsolicited adverse events (AEs) within 30 days after each vaccine dose. Timeframe: During 30 days (Days 0-29) after each vaccination. This typically refers to the documentation and assessment of unexpected adverse events that occur within the 30-day observation period after each vaccine dose, including the frequency of occurrence, severity (such as mild, moderate, and severe), and the investigator's assessment of the association between these events and vaccination. 5. The incidence of serious adverse events (SAEs) from the first dose of vaccination to one month after the final dose. Timeframe: From first vaccination up to 30 days post last vaccination (Month 0-Month 3). Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity. 6. The incidence of potential immune-mediated diseases (pIMDs) from the first dose of vaccination to one month after the final dose. Timeframe: From first vaccination up to 30 days post last vaccination (Month 0-Month 3). Potential immune-mediated diseases (pIMDs) are a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune aetiology.

Patients with severe chronic diseases, including but not limited to severe cardiovascular diseases (pulmonary heart disease, pulmonary edema), severe liver and kidney diseases, and diabetes mellitus with complications; 16. History of thrombocytopenia or other coagulation disorders, which may cause intramuscular injection contraindications; 17.
