Summary

This study is designed to investigate, at first, safety and tolerability of a novel liquid vaccine formulation named MV-ZIKA-RSP, in healthy adults aged 18 to 55 years

Eligibility Criteria

Inclusion Criteria

  • Signed informed consent obtained before any trial-related activities
  • Healthy men or women aged 18 to 55 years on the day of consenting
  • Ability to comprehend the full nature and purpose of the study, including possible risks and side effects; ability to cooperate with the investigator and to comply with the requirements of the entire study
  • All female participants must have a negative urine pregnancy serum pregnancy test at screening
  • Willingness not to become pregnant or to father a child during the entire study period by practising reliable methods of contraception as specified in protocol section 8.11.4
  • Availability during the duration of the trial
  • Normal findings in medical history and physical examination or the investigator considers all abnormalities to be clinically irrelevant
  • Normal laboratory values or the investigator considers all abnormalities to be clinically irrelevant (unless otherwise specified in exclusion criteria)

Exclusion Criteria

  • Participation in another clinical study (including exposure to an investigational medicinal product or device) within one month before the screening visit or planned concurrent participation in another clinical study before completion of the treatment period (day 56)
  • History of immunodeficiency, known human immunodeficiency virus (HIV) infection or current hepatitis B/C infection
  • Strong anamnestic evidence for or confirmed the history of or current infection with Zika- or Dengue-virus
  • History of drug addiction including alcohol dependence within the last 2 years
  • Inability or unwillingness to avoid intake of more than around 20g alcohol per day during 48 hours after each vaccination (equals roughly 0.5 L beer or 0.25 L of wine)
  • Vaccination within 4 weeks prior to first vaccination or planning to receive any non-study vaccine until the end of the treatment period (day 56)
  • Prior receipt of any Zika or Chikungunya vaccine
  • History of moderate or severe arthritis or arthralgia within the past 3 months prior to Screening Visit
  • Recent infection within 1 week prior to Screening Visit (possibility of deferral)
  • Blood donations including plasma donations, 90 days prior to Screening Visit and anticipated blood, plasma, tissue, sperm or organ donation, throughout the study until the end of the treatment period (day 56)
  • Clinically relevant history of renal, hepatic, gastrointestinal, cardiovascular, respiratory, skin, haematological, endocrine, inflammatory, autoimmune or neurological diseases or clinically relevant abnormal laboratory values, that in the opinion of the investigator may interfere with the aim of the study
  • History of neoplastic disease (excluding non-melanoma skin cancer that was successfully treated) within the past 5 years or a history of any haematological malignancy
  • Behavioural, cognitive, or psychiatric condition that in the opinion of the investigator affects the ability of the participant to understand and cooperate with the study protocol
  • History of severe adverse reactions to vaccine administration, including anaphylaxis and related symptoms, such as urticaria, respiratory difficulty, angioedema and abdominal pain to vaccines, or history of allergic reaction likely to be exacerbated by any component of the vaccine
  • History of anaphylaxis to drugs or other allergic reactions, which the investigator considers compromising the safety of the volunteer
  • Abnormal laboratory values which, at the discretion of the investigator should lead to the exclusion of the subject
  • Use of medication during 2 weeks before the first vaccination and throughout the study, which the investigator considers affecting the validity of the study, except hormonal contraception or hormonal replacement therapy in female participants. (Prior to taking any medication within 72 h before study vaccination, the subject should consult the investigator)
  • Use of immunosuppressive drugs like corticosteroids
