Healthy on the basis of a medical evaluation that reveals the absence of any clinically relevant abnormality and includes a physical examination, a gynecological examination, medical history, electrocardiogram, vital signs and the results of blood biochemistry and hematology tests and a urinalysis carried out at screening 8. If the subject is of childbearing potential, agrees to use adequate contraception (oral contraceptives or double barrier method, as described in section 5.2.4, point 7 of the protocol) and not become pregnant for the duration of the study. Exclusion Criteria: 1. Male 2. Female subject without regular menstrual cycle (24-30 days) 3. History of total hysterectomy 4.

A positive pregnancy test or breast feeding at screening 7. A positive HIV-1 or HIV-2 test at trial screening 8. Having vaginitis as observed by local inspection and vaginal swab 9. Recurrent vaginal infections or sexually transmitted diseases within one year prior to vaccination 10. A positive test for Hepatitis A (confirmed by hepatitis A antibody IgM), hepatitis B (confirmed by hepatitis B surface antigen), or hepatitis C (confirmed by hepatitis C virus antibody) infection at trial screening 11.

Serious adverse reactions to vaccines such as, but not limited to, anaphylaxis, urticaria (hives), respiratory difficulty, angioedema, or abdominal pain or a history of anaphylactic reactions 17.
