Outcome Measures

Primary Outcomes (1)

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

    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.

    Six months following vaccination

Secondary Outcomes (1)

  • To investigate the T-cell immune response of ChAdOx1 85A vaccination compared with ChAdOx1 85A vaccination with MVA85A boost vaccination.

    Six months following vaccination

Other Outcomes (1)

  • To conduct further exploratory immunological analyses on samples from vaccinees in this trial.

    Six months following vaccination

Study Arms (4)

Starter Group

EXPERIMENTAL

The first six volunteers will receive one dose of 5x10\^9vp of ChAdOx1 85A intramuscular injection.

Biological: ChAdOx1 85A

Group A

EXPERIMENTAL

12 subjects will receive one dose of 2.5x10\^10vp of ChAdOx1 85A intramuscular injection.

Biological: ChAdOx1 85A

Group B

EXPERIMENTAL

12 subjects will receive one dose of 2.5x10\^10vp of ChAdOx1 85A by intramuscular injection, followed by a boost dose of 1x10\^8pfu of MVA85A by intramuscular injection 56 days later.

Biological: ChAdOx1 85ABiological: MVA85A

Group C

EXPERIMENTAL

12 subjects will receive two doses of 2.5x10\^10vp of ChAdOx1 85A by intramuscular injection at day 0 and day 28, followed by a boost dose of 1x10\^8pfu of MVA85A by intramuscular injection at day 119.

Eligibility Criteria

Age18 Years - 55 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • 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
  • Able and willing (in the Investigator's opinion) to comply with all the trial requirements

You may not qualify if:

  • 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
  • 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 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
