Criteria

Inclusion Criteria:

1. Written informed consent must be obtained before any assessment is performed.

2. Male and female subjects 21 to 50 years of age inclusive and in good health as determined by past medical history, physical examination, vital signs, electrocardiogram, and laboratory tests at screening.

3. Able to communicate well with the investigator, to understand and comply with the requirements of the study.

Exclusion Criteria:

1. Use of other investigational drugs at the time of enrollment, or within 30 days or 5 half-lives of enrollment, whichever is longer; or longer if required by local regulations, and for any other limitation of participation in an investigational trial based on local regulations.

2. History of hypersensitivity to any of the study drugs or to drugs of similar chemical classes.

3. Use of topical corticosteroids or systemic immunosuppression within the last 3 weeks (for topicals) or 3 months (systemic medication)

4. A history of clinically significant ECG abnormalities, or any of the following ECG abnormalities at screening or baseline.

• PR > 220 msec

• QRS complex > 120 msec

• Long QT syndrome

• QTcF > 430 msec males, > 450 females

5. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG (human chorionic gonadotropin) laboratory test (> 10 mIU/mL).

6. Significant medical problems, including but not limited to the following: uncontrolled hypertension (≥160 systolic /95 diastolic mm Hg), congestive heart failure [New York Heart Association status of class III or IV].

7. Screening total WBC count <3,500cells/µL, or platelets <140,000cells/µL or neutrophils <2,000cells/µL or hemoglobin <12 g/dL / <13.5g/dL for female / male.

8. Active systemic infections during the last two weeks (exception: common cold) prior to enrollment.

9. A febrile illness within 72 hours, or major dental work within 8 days, prior to first dosing.

10. History of immunodeficiency diseases, including a positive HIV (ELISA and Western blot) test result.

11. A positive Hepatitis B surface antigen (HBsAg) or Hepatitis C test result.

12. Inability or unwillingness to undergo repeated catheterization and / or venipuncture (e.g., because of poor tolerability or lack of access to veins). Inability or unwillingness of having a skin biopsy if consent was given.

13. Any medical or psychiatric condition or clinical laboratory abnormalities which, in the Investigator's opinion, would interfere with interpretation of study results and/or make the participant likely not to adhere to the protocol or complete the study per protocol.

14. History of venous thrombosis or known genetic predisposition to thromboembolic events

15. Subjects prone to keloid or hypertrophic scar formation or any wound healing disorder as visible by checking the vaccine insertion points on upper arm.

16. Fear of needles (belonephobia)

17. Recent (within the last three [3] years) and/or recurrent history of autonomic dysfunction (e.g., recurrent episodes of fainting, palpitations, etc).

18. Not willing to avoid excessive sun exposure, steam baths, sauna, swimming and other strenuous activities during the study to ensure good scarring.

19. Not willing to refrain from use of skin care products applied on application sites for at least 5 days prior to start of Visit 2.
