TRIAL DESCRIPTION
Public title TaMoVac-01
Official scientific title A Phase I/II trial to assess safety and immunogenicity of i.d. DNA priming, i.m. MVA and i.m. rgp140/GLA-AF boosting in healthy volunteers in Tanzania and to develop further HIV vaccine trial capacity building in Tanzania
Brief summary describing the background and objectives of the trial Availability of safe and efficacious vaccine is an important desired goal. Participation of developing countries in this effort is crucial. Following earlier investments through Swedish and EU support, a phase I/II trial has been concluded in Tanzania. The DNA-prime, MVA-boost was safe and induced strong cellular immune responses. We intend to further explore the safety and immunogenicity of boosting with two doses of rgp140 in the adjuvant GLA-AF, administered IM among the TaMoVac01 volunteers

Women shall have a negative urinary pregnancy test 11. Be willing to practice safe sex for the duration of the study to avoid sexually transmitted infections including HIV. 12. Good health as determined by medical history, physical examination, clinical judgment and by key laboratory parameters as judged by the study physician. 1. At risk of HIV infection as mentioned above in the inclusion criteria 2. Active tuberculosis or other systemic infectious process elicited by review of systems, physical examination and laboratory detection (for example detection of Hepatitis B surface antigen, or active syphilis). 3.
