Exclusion Criteria:

  • History of known CHIKV infection;
  • Plans to travel to areas with active CHIKV transmission during the course of the study or history of travel to an endemic CHIKV area within 4 weeks prior to study enrollment;
  • Participation in a clinical study involving an investigational CHIKV vaccine;

  • Positive test results for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV);
  • (1) Abnormal laboratory liver function values (≥ grade 1), (2) any grade 1 abnormal lab values deemed clinically relevant by the Investigator, and (3) any ≥ grade 2 abnormal lab values irrespective of clinical significance at screening;
  • Clinically significant abnormal ECG at screening;
  • History of significant cardiovascular, respiratory (including asthma), metabolic, neurological, hepatic, rheumatic, autoimmune, hematological, gastrointestinal or renal disorder;
  • History of immune-mediated or clinically significant arthritis/arthralgia;
  • History of malignancy other than squamous cell or basal cell skin cancer, unless there has been surgical excision that is considered to have achieved a cure;

  • History of severe hypersensitivity reactions or anaphylaxis;
  • History of any vaccine related contraindicating event (e.g., anaphylaxis, allergy to components of the candidate vaccine, other known contraindications);

5. Study Description

Brief Summary
Randomized, observer-blinded, multicenter, dose-escalation Phase 1 clinical study investigating three dose levels of VLA1553 after a single immunization. 120 study participants will be enrolled into the study to receive three different doses (30 subjects in the low and medium and 60 subjects in the high dose group). Vaccination will be given intramuscularly on Day 0. As safety precaution, the study will begin with enrolment of 20 sentinel subjects in an open-label fashion. Thereafter, subjects will be enrolled in a blinded, randomized manner in the three study arms. A re-vaccination will be given at Month 6 or Month 12 to confirm that a single vaccination will be sufficient to induce high titer neutralizing antibodies and protect subjects from CHIKV viremia. Study participants will be followed up until 13 months after initial vaccination.
