入选标准
- •Subjects who, in the opinion of the investigator can and will comply with the requirements of the protocol.
- •Male or female adults ≥18 years of age at time of first study vaccination.
- •Written informed consent obtained from the subject.
- •Subjects who are at risk of occupational exposure to H5N1 influenza viruses based on exposure, or potential exposure during either (a) laboratory operations with live H5N1 virus, (b) production of H5N1 vaccines, or (c) conduct of epidemiological investigations of H5N1 cases.
- •Stable health status as defined by absence of a health event satisfying the definition of a serious adverse event, or a change in an ongoing drug therapy due to therapeutic failure or symptoms of drug toxicity, within 30 days prior to enrollment.
- •Female subjects of non-childbearing potential may be enrolled in the study. Non-childbearing potential is defined as current tubal ligation, hysterectomy, ovariectomy or post-menopause.
- •Female subjects of childbearing potential may be enrolled in the study, if they have practiced adequate contraception for 30 days prior to vaccination, and have a negative pregnancy test on the day of vaccination, and agree to practice adequate contraception for two months following the last dose of vaccine.
排除标准
- •Presence or evidence of neurological or psychiatric diagnoses which, although stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
- •Presence of a temperature ≥ 38.0ºC (≥100.4ºF) or acute symptoms greater than "mild" severity on the scheduled date of first vaccination.
- •NOTE: The subject may be vaccinated at a later date, provided symptoms have resolved, vaccination occurs within the window specified by the protocol, and all other eligibility criteria continue to be satisfied.
- •Significant risk of complications from intramuscular injections due to disorder of coagulation. Persons receiving prophylactic antiplatelet medications, e.g., low-dose aspirin, and without a clinically-apparent bleeding tendency, are eligible. Assessment of risk of injection complications should be made in the context of individual subject risk of H5N1 virus infection.
- •An acute evolving neurological disorder or Guillain Barré Syndrome within 42 days of receipt of prior seasonal or pandemic influenza vaccine.
- •Administration of an inactive vaccine within 14 days or of a live attenuated vaccine within 30 days before the first dose of study vaccine.
- •Planned administration of any vaccine other than the study vaccine before Day
- •Any known or suspected allergy to any constituent of influenza vaccines or component used in the manufacturing process of the study vaccine including a history of anaphylactic-type reaction to consumption of eggs; or a history of severe adverse reaction to a previous influenza vaccine.
- •Known pregnancy or a positive urine beta-human chorionic gonadotropin (β-hCG) test result before the first vaccination.
- •Lactating or nursing women.
- •Any condition which, in the opinion of the investigator, prevents the subject from participating in the study.
结局指标
主要结局
Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms Overall and by Age Category (18-64 and >64 Years of Age).
时间窗: During a 7-day follow-up period (Days 0-6) after each vaccination
Solicited local symptoms assessed were pain, redness and swelling. Any was defined as any solicited local symptom reported irrespective of intensity. Grade 3 pain was defined as significant pain at rest that prevented normal everyday activities. Grade 3 redness and swelling was greater than 100 millimeters (mm) i.e. \>100mm.
Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms Overall and by Age Category (18-64 and >64 Years of Age).
时间窗: During a 7-day follow-up period (Days 0-6) after each vaccination
Solicited general symptoms assessed were fatigue, gastrointestinal symptoms, headache, joint pain, muscle ache, shivering, sweating and fever \[oral temperature above 38.0 degrees Celsius (°C)\]. Gastrointestinal symptoms included nausea, vomiting, diarrhea and/or abdominal pain. Any = any solicited general symptom reported irrespective of intensity and relationship to vaccination. Related = symptoms considered by the investigator to have a causal relationship to vaccination. Grade 3 symptoms = symptoms that prevented normal activity. Grade 3 fever = axillary temperature ≥ 39.0°C and ≤40°C.
Number of Subjects Reporting Any Unsolicited AEs, Overall and by Age Category (18-64 and >64 Years of Age)
时间窗: During the 21-day (Days 0-20 post dose 1 and Days 21-41 post dose 2) post-vaccination period
Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as occurrence of any unsolicited symptom regardless of intensity grade or relation to vaccination. Related was defined as an unsolicited symptom assessed as causally related to the study vaccination.
