Abstract:
This thesis describes work undertaken by the author at the University of Oxford. It begins by providing an introduction to malaria infection and pathophysiology, and a review of the latest attempts to produce an effective malaria vaccine. It goes on to describe the rationale behind the vaccines developed by the University of Oxford and others. A brief introduction to the process of planning and carrying out clinical trials of vaccines is then provided, and is followed by chapters describing two clinical trials, designed to test the safety, immunogenicity and then efficacy of candidate malaria vaccines. These trials were performed in Oxford, to examine two different vaccination approaches. The first intended to broaden the specificity of the vaccine induced immune response, by providing multiple antigens in one vaccine, aiming thereby to improve protection from malaria infection. The second regimen used a combination vaccine intending to induce both humoral and cellular immunity simultaneously, thereby providing enhanced efficacy against malaria infection. Neither approach was sufficient to provide protection from infection in the challenge studies described; however, some impact on the disease was detected in the second study. This is examined in detail. The laboratory work described studies background immune responses (both cellular and humoral) to vaccine antigens in a malaria exposed population, intended to support the inclusion of these antigens in the multi-antigen vaccine. The remaining chapters describe work in parasite life cycle modelling, undertaken to aid interpretation of results of these clinical trials, and finally an examination of the clinical course of malaria in the control volunteers who have taken part in the many challenge studies conducted in Oxford.
