Dataset from A Phase I Trial Evaluating Mucosal Administration of a Candidate TB Vaccine, MVA85A, as a Way to Induce Potent Local Cellular Immune Responses and Avoid Anti-vector Immunity

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.
