Eligibility Criteria

Inclusion Criteria

•Subjects must meet all of the following criteria to enter the trial:
•Healthy adult aged 18-55 years
•Resident in or near Oxford (for CCVTM) or Birmingham (for WTCRF) and able to travel to Oxford for vaccinations 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

Exclusion Criteria

•Subjects must meet none of the following criteria to enter the trial:
•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
•Shared a residence within one year prior to day 0 with an individual on anti-tuberculosis treatment or with culture- or smear-positive pulmonary tuberculosis
•Previous vaccination with any recombinant MVA, FP or adenoviral vector
•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 including eggs
•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

Outcomes

Primary Outcomes

Safety of ChAdOx1 85A vaccination with, and without, MVA85A boost vaccination in healthy, BCG vaccinated adults.

Time Frame: Six months following vaccination

To evaluate the safety in healthy BCG-vaccinated subjects of ChAdOx1 85A vaccination, with and without MVA85A boost vaccination, by actively and passively collecting data on adverse events.

Secondary Outcomes

To investigate the T-cell immune response of ChAdOx1 85A vaccination compared with ChAdOx1 85A vaccination with MVA85A boost vaccination.(Six months following vaccination)
