Brief Summary
The clinical study primarily assesses the safety of MV-CHIK a new Chikungunya vaccine in a previously epidemic area in healthy volunteers. Secondarily, immune response and viremia will be assessed. MV-CHIK will be compared to the commercially available MMR vaccine. 80% of the subjects will receive MV-CHIK; 20% will receive MMR vaccine.

Outcome Measures
Primary Outcomes (1)
Number of Participants With AEs and Abnormal Lab Values, Vital Signs, and PE Findings
Number of solicited and unsolicited adverse events and number of grade 2 and higher solicited and unsolicited adverse events including clinically significant abnormal safety laboratory results, vital signs, and physical examination findings in previously exposed versus unexposed individuals.
Throughout the whole study period (until day 392 after first dose)
Secondary Outcomes (1)
Immunogenicity
Days 0, 28, 56, 168, 280, and 392
Study Arms (2)
MV-CHIK and Placebo
EXPERIMENTALSubjects will receive two injections on study day 0 and one injection on day 28. On both days they will receive a 5E+05 (+/- 0.5 log) TCID50 intramuscularly in the deltoid muscle of one arm. On day 0 they will receive a dummy injection of placebo (physiological saline) subcutaneously in the contralateral arm.
MMR-vaccine and Placebo
ACTIVE COMPARATORSubjects will receive two injections on study day 0 and one injection on day 28. On both days they will receive dummy injections of placebo (physiological saline) in the deltoid muscle of one arm. On day 0 they will receive MMR-vaccine subcutaneously in the contralateral arm.
Interventions
Lyophilized, life attenuated, measles vectored Chikungunya vaccine; 5E+05 TCID50 (+/- 0.5 log) per dose
Lyophilized mixture of life attenuated Measles, Mumps, and Rubella viruses; 1000, 12500, and 1000, respectively, TCID50 per dose
Eligibility Criteria
You may qualify if:
- Aged ≥21 to ≤50 years on the day of enrollment.
- Able to provide informed consent.
- Available and accessible for the duration of the trial.
- Able and willing to comply with all requirements of the study.
- For female subjects, willing to practice a reliable form of contraception as specified in the protocol until five months after the second and final vaccination in accordance with recommendations following MMR vaccination.
- Medical history and physical examination findings are considered normal or not clinically significant in the opinion of the Investigator.
- Laboratory values are considered normal or not clinically significant in the opinion of the Investigator.
- History of previous measles vaccination, either in childhood or as an adult if more than three months before participation in this study.
You may not qualify if:
- Taking medication or other treatment for unresolved symptoms attributed to a previous chikungunya virus infection.
- Prior receipt of any chikungunya or other alphavirus vaccine.
- Recent infection, including suspected chikungunya (within 1 week prior to Screening Visit).
- History of an allergic or anaphylactic reaction to any vaccine.
- An allergic reaction other than allergic contact dermatitis to any component of either vaccine (i.e., neomycin, gelatin), or a current egg allergy. Volunteers with a childhood history of egg allergy who are able to tolerate egg in their diet now will not be excluded on this basis.
- History of an immunosuppressive disorder (such as human immunodeficiency virus \[HIV\] infection, common variable immunodeficiency), chronic infection (such as chronic hepatitis B or C), autoimmune disease (such as rheumatoid arthritis, systemic lupus erythematosus \[SLE\], autoimmune thyroid disease) or any medical condition that, in the opinion of the Investigator, could lead to an atypical immune response to the vaccine.
- History of moderate or severe non-traumatic arthritis or arthralgia within 3 months of the Screening Visit.
- Recent (within 30 days), current or anticipated use of any immunosuppressive or immune modifying medication including corticosteroids (excluding nasal, ophthalmic, and other topical preparations).
- Other vaccination or planned vaccination within 4 weeks of either study dose (seasonal influenza vaccine excepted).
- Measles vaccination or booster within the last 3 months or planned during the clinical study.
- Receipt or planned receipt of blood products including immunoglobulins within 120 days of the Screening Visit.
- Pregnant or lactating or planning pregnancy during the trial.
- Known alcohol or other substance abuse that in the opinion of the Investigator affects the ability or willingness of the participant to understand and comply with the study protocol.
- Participation in another clinical study within the past 30 days in which the subject was exposed to an investigational product (pharmaceutical product or placebo or device) or planned concurrent participation in another clinical study during the study period.
- Relevant history of any medical condition that, in the opinion of the Investigator, may interfere with the safety of the subject (volunteer) or aims of the study.

- All subjects will receive two intramuscular injections on day 0 and 28 and one subcutaneous injection on day 0. Subjects randomized to verum will receive MV-CHIK intramuscularely on days 0 and 28 and placebo subcutaneously in the contralateral arm on day 0. Subjects randomized to the comparator will receive MMR-vaccine subcutaneously on day 0 and placebo (dummy injection) intramuscularely on days 0 and 28 in the contralateral arm.
