Study Evaluating Aerosol and Intradermal Administration of a Candidate Tuberculosis (TB) Vaccine, MVA85A, as a Way to Increase Immune Response and Avoid Anti-vector Immunity

Summary

Boost vaccinations sometimes have no effect because the body has got used to the vaccine and no longer reacts to it. We are therefore investigating whether vaccinating with aerosolised MVA85A (a candidate tuberculosis vaccine) followed by a boost MVA85A intradermal vaccination (or vice versa) avoids this and increases the immune response to vaccination.
