Safety, Tolerability and Immunogenicity of Novartis Meningococcal B Recombinant Vaccine Administered to Healthy Adolescents According to Different Vaccination Schedules

The proposed study is aimed to assess the antibody response and short-term persistence of Novartis Meningococcal B Vaccine after one, two or three doses and to evaluate the optimal vaccination schedule in an adolescent population.

1. History of any meningococcal B vaccine administration;
2. Current or previous, confirmed or suspected disease caused by N. meningitidis;
3. Household contact with and/or intimate exposure to an individual with any laboratory confirmed N. meningitidis infection within 60 days of enrollment;

5. Antibiotics within 6 days prior to enrollment;
6. Pregnancy or nursing (breastfeeding) mothers;

8. Any serious chronic or progressive disease (e.g., neoplasm, diabetes, cardiac disease, hepatic disease, progressive neurological disease or seizure disorder; autoimmune disease, HIV infection or AIDS, or blood dyscrasias or diathesis, signs of cardiac or renal failure or severe malnutrition).
9. Known or suspected impairment/alteration of the immune system, immunosuppressive therapy, including use of corticosteroids in immunosuppressive doses or chronic use of inhaled high-potency corticosteroids within the previous 60 days. \[Use of topical corticosteroids administered during the study in limited areas (i.e., eczema on knees or face or elbows) of the body is allowed\]; immunostimulants;
10. Receipt of blood, blood products and/or plasma derivatives, or a parenteral immunoglobulin preparation within the previous 90 days;
11. History of severe allergic reactions after previous vaccinations or hypersensitivity to any vaccine component;
12. Receipt of or intent to immunize with any other vaccine(s) within 30 days prior (60 days for live viral vaccines) and throughout the study period (exception: licensed fluvaccine should not be administered within 14 days prior to enrollment; routine vaccine administration may be administered after the blood draw at Study Month 7);
13. Participation in another clinical trial within the last 90 days or planned for during study;
14. Family members and household members of research staff;
15. Any condition which in the opinion of the investigator and/or the Regional MD may interfere with the evaluation of the study objectives.
