| Eligibility | Inclusion Criteria: 1. Healthy adult female volunteers (as determined by medical history, physical examination, laboratory test values, vital signs and electrocardiograms [ECGs] at screening) aged 18 - 40 years. 2. Body mass index (BMI) = 18 and = 30 kg/m2. 3. Volunteers weight = 50kg and =100kg at screening. 4. Able to voluntarily provide written informed consent to participate in the study. 5. Must understand the purposes and risks of the study and agree to follow the restrictions and schedule of procedures as defined in the protocol. 6. Volunteers must be pre-menopausal. Volunteers who have had a hysterectomy will have pre-menopausal status confirmed by a FSH and oestradiol test. 7. Females of childbearing potential must have a negative pregnancy test at screening (ß HCG) and prior to each dose and must be willing to use an adequate and highly effective method of contraception until at least Day 85 of the study. A highly effective method of birth control is defined as one which results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as sterilisation, implants, injectables, combined oral contraceptives, IUDs (Intrauterine Device), condoms, occlusive caps (cervical/vault caps) with spermicidal foam/gel/ film/cream/suppository. True sexual abstinence is acceptable when this is in line with the preferred and usual lifestyle of the volunteer (periodic abstinence e.g. calendar, ovulation, symptothermal, post-ovulation methods, declaration of abstinence for the duration of the trial, and withdrawal are not acceptable methods of contraception) 8. In Part A: Volunteers must be non-smokers for at least 3 months prior to first studyvaccine administration. In Part B: Volunteers may be light smokers i.e. up to a maximum of 5 cigarettes per day or nicotine equivalent. 9. Must be willing to consent to have data entered into The Over Volunteering Prevention System (TOPS). 10. The volunteer's primary care physician has confirmed within the last 12 months that there is nothing in their medical history that would preclude their enrolment into a clinical trial. Exclusion Criteria: 1. Volunteers with history or presence of significant cardiovascular disease, pulmonary, hepatic, gallbladder or biliary tract, renal, haematological, gastrointestinal, endocrine, immunologic, dermatological, neurological, psychiatric, autoimmune disease or current infection. 2. Pregnant or lactating females. 3. Laboratory values at screening which are deemed to be clinically significant, unless agreed in advance by the Sponsor's Responsible Medic and Principal Investigator. 4. Current or history of drug or alcohol abuse, or a positive alcohol breath test prior to first dosing. 5. Positive for human immunodeficiency virus (HIV), hepatitis B or hepatitis C. 6. Participation in a clinical drug study during the 90 days preceding the initial dose in this study. 7. Any significant illness during the 4 weeks preceding check-in for this study (Day 1). 8. Volunteers with a history of severe allergic reactions after previous vaccination. 9. Volunteers who have received any vaccine within 30 days of screening, or who are planning to receive a vaccine up to Day 85 of the study. 10. Volunteers receiving immunosuppressive therapy (e.g. systemic steroids, cancer therapies, methotrexate, azathioprine) in the 6 months prior to screening, antibiotics within 10 days of receiving the first dose or taking any short-term medications including over-the-counter preparations, vitamins, herbal and/or mineral supplements within 7 days of the first dose. Chronic medications such as antihypertensives, bronchodilators, oral contraceptives or statins that do not affect the immune system, will be permitted and allowed to continue during the study at the discretion of the Investigator. Paracetamol will be permitted for the treatment of headache or other symptoms. 11. Volunteers with tattoos at the proposed site of vaccine administration. 12. Donation of blood or blood products within 90 days prior to vaccine administration. 13. Volunteers who, in the opinion of the Investigator, are unsuitable for participation in the study. |
