• Able and willing to provide informed consent voluntarily signed by participant.
• Any gender, 18 to 45 years of age (inclusive).
• Generally healthy, in the opinion of the Investigator, based on medical history, physical examination, and screening laboratory assessments.
• Women who are either:
• (i). Not of childbearing potential (CBP): pre-menarche, anatomically sterile, or post-menopausal (defined as ≥12 months without menses) or (ii). Meeting all the following criteria: Negative urine pregnancy test at screening visit; and Negative urine pregnancy test immediately prior to dosing at Day 1; and using an acceptable method of contraception (if female of childbearing potential) for the duration of participation, such as: Hormonal contraceptives (e.g., implants, pills, patches) initiated ≥ 30 days prior to dosing or; Intrauterine device (IUD) inserted ≥30 days prior to dosing or; double barrier type of birth control (male condom with female diaphragm, male condom with cervical cap).

You may not qualify if…

• Currently pregnant, breastfeeding, or planning to become pregnant during the study.
• Body Mass Index (BMI) ≥35 kg/m2.
• Positive laboratory evidence of current infection with human immunodeficiency virus (HIV-1, HIV-2), hepatitis C virus (HCV) or hepatitis B virus (HBV).
• History of severe allergic reaction or anaphylaxis to any component of the investigational product (IP).
• History of known congenital or acquired immunodeficiency that could impact response to vaccination (e.g., leukemia, lymphoma, generalized malignancy, functional or anatomic asplenia, alcoholic cirrhosis).
• Prior or anticipated receipt of immunomodulatory or immunosuppressive therapy from six months prior to screening through Day 64.
• Receipt or anticipated receipt of blood or blood-derived products from 90 days prior to screening through Day 64.
• Acute disease within the last 14 days (participants with an acute mild febrile illness can be considered for a deferral of vaccination two weeks after the illness has resolved and treatment has been completed).
• Clinically significant cardiac, pulmonary, respiratory, rheumatologic, or other chronic disease, in the opinion of the Investigator. This may include chronic illness requiring hospitalization in the last one month prior to screening.
• Enrollment in an interventional study and/or receipt of another investigational product from 30 days prior to screening through the duration of study participation.
• Receipt or anticipated receipt of any vaccine from 30 days prior to screening through Day 64.
• Prior receipt of an investigational CHIKV vaccine/product.
• Detectable baseline anti-CHIKV IgG antibody as determined by ELISA.
• Any other condition that, in the opinion of the investigator, could adversely impact the participant's participation or the conduct of the study, creates an unacceptable risk to the participant, or may interfere with the conduct of the study or validity of the data.
• Restricted venous access that would prevent the collection of plasma and serum necessary for participation.
• Weight <110 pounds.
