Safety and Immunological Response of a Boosting Dose of MVA-B in Healthy Volunteers After 4 Years of Receiving MVA-B

Summary

24 healthy male and female volunteers who are at low risk of HIV infection and entered into the RISVAC02 study and were randomly allocated to receive 3 intramuscular injections of MVA-B at weeks 0, 4 and 16 will receive a boosting dose 4 years thereafter. Participants will attend one of two clinical centres on at least 5 occasions over 16 weeks. These visits will comprise: * Screening * Trial entry and boosting immunisation * Early follow-up after immunisation * Follow-up x 2 including the final visit Participants will have blood and urine collected, and receive 1 immunisation. They will be counselled prior to and following a HIV test, and given health education on prevention of sexually transmitted infections including HIV. T The two centres which participate are: * Hospital Clinic, Barcelona and * Hospital Gregorio Marañón, Madrid The primary objective is to explore the safety and immunogenicity of MVA-B.
