Brief summary: This is a phase I trial to compare the safety and immunogenicity of candidate TB vaccine MVA85A administered by the aerosol inhaled route and the intradermal route in healthy BCG-vaccinated adult subjects.


Eligibility criteria: Inclusion Criteria:

* Healthy adults aged 18-50 years
* Resident in or near Oxford for the duration of the trial period
* No relevant findings in medical history or on physical examination
* Confirmation of prior vaccination with BCG not less than 6 months prior to projected trial vaccination date (by visible BCG scar on examination or written documentation)
* Allow the Investigators to discuss the individual's medical history with their GP
* Use effective contraception for the duration of the trial period (females only)
* Refrain from blood donation during the trial
* Give written informed consent
* Allow the Investigator to register subject details with a confidential database to prevent concurrent entry into clinical trials
* Able and willing (in the Investigator's opinion) to comply with all the trial requirements

Exclusion Criteria:

* Any respiratory disease, including asthma
* Current smoker
* Clinically significant abnormality on screening chest x rays
* Clinically significant abnormality of pulmonary function tests
* Any nasal, pharyngeal, or laryngeal finding which precludes bronchoscopy
* Current use of any medication taken through the nasal or inhaled route including cocaine or other recreational drugs
* Laboratory evidence at screening of latent M.tb infection as indicated by a positive ELISPOT response to ESAT6 or CFP10 antigens
* Clinical, radiological, or laboratory evidence of current active TB disease
* Previous vaccination with candidate vaccine MVA85A or candidate vaccine FP85A or any other recombinant MVA vaccine
* Clinically significant history of skin disorder, allergy, immunodeficiency (including HIV), cancer (except BCC or CIS), cardiovascular disease, gastrointestinal disease, liver disease, renal disease, endocrine disorder, neurological illness, psychiatric disorder, drug or alcohol abuse
* History of serious psychiatric condition
* Concurrent oral or systemic steroid medication or the concurrent use of other immunosuppressive agents
* History of anaphylaxis to vaccination or any allergy likely to be exacerbated by any component of the trial vaccine, sedative drugs, or any local or general anaesthetic agents
* Any abnormality of screening blood or urine tests that is deemed to be clinically significant or that may compromise the safety of the subject in the trial
* Positive HBsAg, HCV or HIV antibodies
* Female currently lactating, confirmed pregnancy or intention to become pregnant during trial period
* Use of an investigational medicinal product or non-registered drug, live vaccine, or medical device other than the trial vaccine for 30 days prior to dosing with the trial vaccine, or planned use during the trial period
* Administration of immunoglobulins and/or any blood products within the three months preceding the planned trial vaccination date
* Any other significant disease, disorder, or finding, which, in the opinion of the Investigator, may either put the subject at risk or may influence the result of the trial or may affect the subject's ability to participate in the trial
