Eligibility Criteria

18 Years - 30 Years (Adult)All SexesAccepts Healthy Volunteers

  • Other AE following immunization, at least possibly related to previous receipt of any vaccine.
  • Suspected or known hypersensitivity to any of the study vaccine components, including chicken or egg protein.

  • Acute or chronic clinically significant pulmonary, cardiovascular, hepatobiliary, metabolic, neurologic, psychiatric or renal functional abnormality, as determined by medical history, physical examination or clinical laboratory screening tests, which in the opinion of the investigator, might interfere with the study objectives.
  • History of any blood or solid organ cancer.
  • History of thrombocytopenic purpura or known bleeding disorder.
  • History of seizures.
  • Known or suspected immunosuppressed or immunodeficient condition of any kind.
  • Known chronic HBV or HCV infection.
  • Known active tuberculosis or symptoms of active tuberculosis, regardless of cause.
  • History of chronic alcohol abuse and/or illegal drug use.
  • Pregnancy or lactation. (A negative pregnancy test will be required before administration of study product for all women of childbearing potential.)
  • History of Guillain-Barré Syndrome
  • Any condition that, in the opinion of the investigator, would increase the health risk to the subject if he/she participates in the study or would interfere with the evaluation of the study objectives.

Outcomes

Primary Outcome Measures

Immediate Reactions Occurring Within 60 Minutes of Administration of Any Dose
Data presented are after 1st and 2nd vaccination combined. All participants were observed for immediate reactions for 60 minutes after administration of study product, with appropriate medical treatment readily available in case of an anaphylactic reaction following the administration of study product.
Number of Participants With at Least One Solicted Reactogenicity After Both Injections
Data presented are after 1st and 2nd vaccination combined. Solicted reactogenicity are local and systemic events that are expected after injection and specifically asked of the participant. Only reported reactogenicity is presented. If not shown, then no participant reported that reaction in any study group. Local reactions are redness, swelling, pain, tenderness, and hardness. Systemic reactions are actual and subjective fever, chills, cough, difficulty breathing, runny nose, nasal congestion, sore throat, hoarseness of voice, headache, confusion. convulsions/seizures, fatigue/malaise, muscle aches (generalized), joint pain, pink or red eyes, sore eyes, itchy eyes, drainage from eyes. ear pain or discharge, rash, abdominal pain, diarrhea, vomiting, and jaundice.
Number of Participants With at Least One Unsolicited AE
Summary of number of participants with at least one unsolicited AE after 1st and 2nd vaccination combined. Please see the adverse event section of this report for full details.
All Serious Adverse Events (SAEs) Occurring Within 3 Weeks of Receipt of Any Dose
Summary data. Data presented are after 1st and 2nd injections combined. Please see AE reporting section of this report for full details.

Secondary Outcome Measures

The Proportion of Subjects Achieving a Hemagglutination Inhibition (HAI) Titer ≥ 1:40 Pre-vaccination (Day 0) to Post 2nd Vaccination (Day 49)
The Proportion of Subjects Achieving a Four-fold Rise in HAI Between Doses or From Baseline to Post-Injection 2
Geometric Mean Titer (GMT) of Hemagglutination Inhibition After Each Dose

5. Study Description

Brief Summary
This is a first-in-human study of safety and immunogenicity of an A/H5N1 inactivated whole cell vaccine when given in two injections in two doses (low and high) compared to a placebo in 76 healthy adult subjects in Vietnam. Vaccine and placebo are manufactured by the IVAC in Vietnam.
Detailed Description
This is a phase 1, double blinded, randomized, placebo-controlled study. Seventy-six healthy male and female adults, 18 to 30 years of age, will be enrolled into the trial. Subjects will be randomized to one of three treatment allocations: 32 subjects to 7.5 mcg/dose vaccine (low dose), 32 subjects to 15 mcg/dose vaccine (high dose) and 12 subjects to placebo. This sample size was selected to enable at least 30 evaluable subjects in each of the groups receiving active vaccine. The study will utilize a "block randomization" to assure a balance of 8:8:3 vaccine and placebo when all subjects are enrolled. The study will be double blinded, meaning the study subjects, investigators, and the sponsor will be unaware of the treatment allocated to each subject until the clinical trial database is declared final and locked. Since this is a first-in-human study, all injections of study product will be sequential and staggered and there will be a safety evaluation between a sentinel cohort of 19 subjects and the remaining 57 study subjects for both the 1st and 2nd doses in the study. A sentinel group of 19 participants' enrollment and vaccination will precede the remainder of the study group by approximately 2-3 weeks. Product administration for both injections of vaccine or placebo will be sequential and staggered.
