Outcome Measures

Primary Outcomes (1)

  • Percent of Participants of Definite Hepatitis E by Category and Immunological Markers (Anti HEV) During the Follow-up Period

    Percent of participants of definite hepatitis E by category and immunological markers (anti HEV) during the follow-up period. * Illness for at least 3 days comprised of at least 3 of the following symptoms: fatigue, loss of appetite, abdominal discomfort, right upper quadrant pain, nausea, vomiting * Peak of Alanine Aminotransferase (ALT) greater then 2.5 times the upper limit of normal (2.5 x 42 =105) * Percent of Participants = n x 100 / N

    14 days after dose 3 at 6 months

Secondary Outcomes (2)

  • Percent of Participants of Definite Hepatitis E Disease by Category During the Follow-up Period

    14 days after dose 2 until 14 days after dose 3

  • Number of Suspected, Definite, Probable and Not Confirmed Hepatitis E Disease Cases

    before dose 1 thru 14 days after dose 3

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • A male or female 18 years of age or older at the time of the first vaccination.
  • Written or oral witnessed (if the subject was illiterate) informed consent obtained from the subject
  • Free of obvious health problems as established by medical history before entering into the study
  • If the subject was female, she must have a negative serum pregnancy test within 48 hours prior to each vaccination and must agree to avoid becoming pregnant during the course of vaccination and until 30 days after the last dose of vaccine.

You may not qualify if:

  • Use of any investigational or non-registered drug or vaccine other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period.
  • Administration of chronic (defined as more than 14 days) immunosuppressants or other immune modifying drugs within six months of vaccination. For corticosteroids, this will mean prednisone, or equivalent, \* 0.5 mg/kg/day. Inhaled and topical steroids are allowed.
  • Any chronic drug therapy to be continued during the study period with the exception of contraceptive agents, homeopathic remedies, vitamins, minerals and any other dietary supplements or other drug therapy at the discretion of the investigator.
  • Planned administration/administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of study vaccine, excluding tetanus toxoid or rabies vaccine.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection, as reported by the volunteer (testing for HIV will not be performed).
  • History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
  • Major congenital defects or serious chronic illness.
  • History of any neurologic disorders or seizures.
  • Acute disease at the time of enrollment. Acute disease was defined as the presence of a moderate or severe illness with or without fever. All vaccines could be administered to persons with a minor illness such as diarrhea, mild upper respiratory infection with or without low-grade febrile illness, i.e., oral temperature \< 38.0°C (100.4°F).
  • Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by history.
  • Administration of immunoglobulins and/or any blood products within the three months preceding the first dose of study vaccine or planned administration during the study period.
  • Pregnant female.
  • History of chronic alcohol consumption (defined as the consumption of the equivalent of 4 or more 12 ounce beers 4 or more times a week) and/or intravenous drug abuse.
  • Antibodies to rHEV (\* 20 WR U/mL).
