Interventions
A single dose of 0.5 mL of the dengue vaccine was injected subcutaneously into the upper-outer triceps/deltoid area of the non-dominant arm at Day 0 and at 6 months.
A single dose of 0.5 mL of the dengue vaccine was injected subcutaneously into the upper-outer triceps/deltoid area of the non-dominant arm at Day 0 and at 6 months.
A single dose of 0.5 mL of the placebo sterile solution of buffer identical in appearance to vaccine)was injected subcutaneously into the upper-outer triceps/deltoid area of the non-dominant arm at Day 0 and at 6 months.
Eligibility Criteria
You may qualify if:
- A healthy male or female adult 20-25 years of age (≥20 years of age and ≤25 years of age) at the time of vaccination;
- Free of obvious health problems as established by medical history and physical examination before entering into the study;
- Written informed consent obtained from the subject;
- Able to read the Subject Information Sheet and Consent Form;
- Subjects who the investigator believes can and will comply with the requirements of the protocol (e.g., completion of the diary cards, return for follow-up visits) should be enrolled in the study;
- females must be of non-childbearing potential, i.e. surgically sterilized or, if of childbearing potential, she must be abstinent or on adequate contraceptive precautions (i.e. intrauterine contraceptive device; oral contraceptives or other equivalent hormonal contraception, e.g. progestin implantable, cutaneous hormonal patch or injectable contraceptives) for 30 days prior to vaccination, have a negative pregnancy test within 48 hours prior to vaccination and must agree to continue such precautions for 60 days after completion of the vaccination series
You may not qualify if:
- Pregnant or lactating female, planning to become pregnant or planning to discontinue abstinence or contraceptive precautions;
- History of any neurological or behavioral disorder or seizures, with the exception of a single febrile seizure in childhood;
- History of drug abuse or alcohol consumption (more than 2 drinks per day);
- History of allergic disease/reaction likely to be exacerbated by any component of the vaccine;
- Acute or chronic, pulmonary, cardiovascular, hepatic, renal, hematologic or endocrine functional defect, as determined by physical examination or laboratory tests;
- Any confirmed or suspected immunosuppressive or immunodeficient condition or seropositive for HBsAg, anti-HCV or anti-HIV;
- Acute disease at the time of enrollment (acute disease is defined as the presence of a moderate or severe illness with or without fever);
- Chronic hepatomegaly, right upper quadrant abdominal pain or tenderness;
- Chronic splenomegaly, left upper quadrant abdominal pain or tenderness;
- Hypertension; chest pain, palpitations, dizziness, shortness of breath, arrhythmias or friction rubs;
- Use of any investigational or non-registered drug or vaccine other than the study vaccine within 30 days preceding the study vaccine (includes placebo) or planned use during the study period;
- Planned administration of a vaccine not foreseen by the study protocol during the period starting from 30 days before the first dose of the study vaccine/placebo and ending 30 days after the second dose;
- A planned move to a location that will prohibit participating in the trial for 9 months after the initial vaccination;
- Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within 90 days preceding the first dose or planned administration during the study period. For corticosteroids, this will mean prednisone, or equivalent, 0.5 mg/kg/day. Inhaled and topical steroids are allowed;
- Administration of immunoglobulins and/or blood products within 90 days preceding the first dose or planned administration during the study period;
- +2 more criteria
