The vaccines are model agents selected as they match antigens but have discordant adjuvants, have a known immunogenicity profile, assays are freely available to measure responses, and they are safe to administer to healthy adults at the doses and schedules proposed. This study will strive to correlate biomarker activity with observed immunological responses to vaccination and if successful, these biomarkers could be used in early stage clinical trials to optimize selection of vaccine candidates with a profile that will be most likely to be effective once they are in generalized use.', 'detailedDescription': 'The purpose of this study is to generate an exploratory training set of data and to identify predictive biomarkers (a measurable biological response that predicts something) of innate and adaptive responses to immunisation of two vaccines utilizing different adjuvant technology given according to approved schedules to healthy adult volunteers.

Following a screening visit, subjects will be randomly allocated to receive three doses of a vaccine at 0, 1 and 2 months. Innate immune responses (cytokine levels and whole blood gene expression) after doses #1 and #3 and adaptive immune responses (serum antibody and antigen specific cellular responses) will be measured at various timepoints after immunisation on an outpatient basis.\n\nThe study is funded by ADITEC, which is a collaborative research programme that aims to accelerate the development of novel and powerful immunisation technologies for the next generation of human vaccines.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.

Known hypersensitivity to any component of the vaccines (excipients: sodium chloride, disodium phosphate dehydrate, sodium dihydrogen phosphate; adjuvants: aluminium phosphate, AS04C, aluminium hydroxide; Hepatitis B antigen produced in yeast cells) or subjects who have exhibited hypersensitivity to any other Hepatitis B vaccine, or a history of any allergy that in the opinion of the investigator would contraindicate subject participation.\n2. Presence of primary or acquired immunodeficiency states with a total lymphocyte count less than 1,200 per mm3 or presenting other evidence of lack of cellular immune competence e.g. leukaemias, lymphomas, blood dyscrasias, or patients receiving immunosuppressive therapy (including regular use of oral, inhaled, topical or parenteral corticosteroids).\n3.
