入选标准
- •Subjects who the investigator believes that they and/or their parent(s) or legally acceptable representative(s) can and will comply with the requirements of the protocol.
- •A male or female child aged between 3 and 8 years inclusive at the time of the first vaccination; children are eligible regardless of history of administration of influenza vaccine in a previous season. However, subjects who have received any seasonal or pandemic influenza vaccine within 6 months preceding the first dose of study vaccine will not be enrolled.
- •Written informed consent obtained from the subject/from the parent(s)/legally acceptable representative(s) of the subject.
- •Written assent obtained from the subject if/as required by local regulations.
- •Subjects in stable health as determined by investigator's clinical examination and assessment of subjects' medical history.
- •Access to a consistent means of telephone contact
排除标准
- •Child in care.
- •Use of an investigational or non-registered product other than the study vaccines within 30 days before study vaccination or planned use during study period. Routine registered childhood vaccinations are permitted.
- •Prior receipt of any seasonal or pandemic influenza vaccine within 6 months preceding the first dose of study vaccine, or planned use of such vaccines during the study period. Prior receipt of more than one dose of a licensed hepatitis A vaccine, with the first dose administered at >=12 months of age.
- •Chronic administration of immunosuppressants or other immune-modifying drugs within 6 months prior to the first vaccine dose.
- •Administration of immunoglobulins and/or any blood products within the 3 months preceding the first dose of study vaccine or planned administration during the study period.
- •History of Guillain-Barre syndrome within 6 weeks of receipt of prior influenza virus vaccine.
- •Any known or suspected allergy to any constituent of influenza vaccines ; a history of anaphylactic-type reaction to constituent of vaccine; or a history of severe adverse reaction to a previous influenza vaccine.
- •Fever at the time of enrolment.
- •Acute disease at the time of enrolment.
- •Any significant disorder of coagulation or treatment with Coumadin derivatives or heparin.
- •Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
- •Ongoing aspirin therapy.
- •Any other condition which, in the opinion of the Investigator, prevents the subject from participating in the study.
研究组 & 干预措施
FluLaval® Quadrivalent Group
Subjects between 3 and 8 years of age at the time of first vaccination received, if primed, 1 dose of FluLaval® Quadrivalent vaccine at Day 0 and, if unprimed, 2 doses of FluLaval® Quadrivalent vaccine at Days 0 and 28. The vaccine was administered intramuscularly in the deltoid muscle of the non-dominant arm.
干预措施: FluLaval® Quadrivalent (Biological)
Havrix Group
Subjects between 3 and 8 years of age at the time of first vaccination received, if primed, 1 dose of Havrix™ vaccine at Day 0 and, if unprimed, 2 doses of Havrix™ vaccine at Days 0 and 28. The vaccine was administered intramuscularly in the deltoid muscle of the non-dominant arm.
干预措施: Havrix™ (Biological)
结局指标
主要结局
Number of Subjects Reporting at Least One Confirmed Occurrence of Influenza A or B.
时间窗: From Day 14 to Day 180
To confirm influenza A and/or B disease, a positive reverse transcriptase polymerase chain reaction (RT-PCR) result for influenza A or B virus from a nose and throat swab obtained concurrently with an influenza like illness (ILI) was required. ILI was defined as the presence of an oral or axillary temperature ≥ 37.8 degrees Celsius (°C) in the presence of at least one of the following symptoms on the same day: cough, sore throat, runny nose or nasal congestion.
