Detailed Description
All vaccinations will be administered intramuscularly. In Groups 1-3, each volunteer will receive one vaccination in total. In Groups 4 and 5, each volunteer will receive two vaccinations in total.
There are five different vaccine schedules:
Group 1 (n=6) will receive 5 x 10^9 vp ChAdOx1 MERS .
Group 2 (n=9) will receive 2.5 x 10^10 vp ChAdOx1 MERS.
Group 3 (n=9) will receive 5 x 10^10 vp ChAdOx1 MERS.
Group 4 (n=6-12) will receive 2.5 x 10^10 vp ChAdOx1 MERS at week 0 followed by a boost of 2.5 x 10^10 vp ChAdOx1 MERS at week 26.
Group 5 (n=6-12) will receive 2.5 x 10^10 vp ChAdOx1 MERS at week 0 followed by a boost of 2.5 x 10^10 vp ChAdOx1 MERS at week 4.
The study will assess the safety of the vaccines, and the immune responses to the vaccinations. Immune responses are measured by tests on blood samples.
Healthy adult volunteers will be recruited in Oxford, England.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
The volunteer must satisfy all the following criteria to be eligible for the study:
- Healthy adults aged 18 to 50 years
- Able and willing (in the Investigator's opinion) to comply with all study requirements
- Willing to allow the investigators to discuss the volunteer's medical history with their General Practitioner or access this medical history electronically.
- For females only, willingness to practice continuous effective contraception during the study and a negative pregnancy test on the day(s) of screening and vaccination
- Agreement to refrain from blood donation during the course of the study
- Provide written informed consent
Exclusion Criteria:
The volunteer may not enter the study if any of the following apply:
- Participation in another research study involving receipt of an investigational product in the 30 days preceding enrolment, or planned use during the study period
- Prior receipt of an investigational vaccine likely to impact on interpretation of the trial data (e.g. Adenovirus vectored vaccine).
- Administration of immunoglobulins and/or any blood products within the three months preceding the planned administration of the vaccine candidate
- Any confirmed or suspected immunosuppressive or immunodeficient state, including HIV infection; asplenia; recurrent, severe infections and chronic (more than 14 days) immunosuppressant medication within the past 6 months (inhaled and topical steroids are allowed)
- History of allergic disease or reactions likely to be exacerbated by any component of the vaccine
- Any history of hereditary angioedema, acquired angioedema, or idiopathic angioedema.
- Any history of anaphylaxis in relation to vaccination
- Pregnancy, lactation or willingness/intention to become pregnant during the study
- History of cancer (except basal cell carcinoma of the skin and cervical carcinoma in situ)
- History of serious psychiatric condition likely to affect participation in the study
- Bleeding disorder (eg. factor deficiency, coagulopathy or platelet disorder), or prior history of significant bleeding or bruising following IM injections or venepuncture
- Any other serious chronic illness requiring hospital specialist supervision
- Suspected or known current alcohol abuse as defined by an alcohol intake of greater than 42 units every week
- Suspected or known injecting drug abuse in the 5 years preceding enrolment
- Seropositive for hepatitis B surface antigen (HBsAg)
- Seropositive for hepatitis C virus (antibodies to HCV)
- Any clinically significant abnormal finding on screening biochemistry or haematology blood tests or urinalysis
- Any other significant disease, disorder or finding which may significantly increase the risk to the volunteer because of participation in the study, affect the ability of the volunteer to participate in the study or impair interpretation of the study data
- Inability of the study team to contact the volunteer's GP to confirm medical history and safety to participate
- Prior exposure to MERS-CoV (serology will be requested at the discretion of the investigator)
- History of allergic reaction to Aminoglycoside antibiotics
