5. Agreement to refrain from blood donation during the course of the study
6. Willing and able to give informed consent for participation in the study
7. For women of childbearing potential only (As defined by protocol section 8.4): Willing to use effective contraception as defined from one month prior to receiving the first vaccine and for the duration of the study AND a negative pregnancy test on the days of screening and vaccination.

2. Planned receipt of another adenoviral vectored vaccine (e.g. Oxford/AstraZeneca or Janssen COVID-19 vaccines) within 90 days of any study vaccine.
3. Previous immunisation with an investigational MERS vaccine
4. History of prior confirmed or suspected MERS infection
5. Administration of immunoglobulins and/or any blood products within the three months preceding the planned administration of the vaccine candidate
6. Any confirmed or suspected immunosuppressive or immunodeficient state, including HIV infection; asplenia; severe infections or receipt of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 12 months or long-term systemic corticosteroid therapy (including for more than 7 days consecutively within the previous 3 months)
7. History of allergic disease or reactions likely to be exacerbated by any component of the vaccine including hypersensitivity to the active substance or to any of the excipients of the IMP or Vaxzevria (i.e. the Oxford/AstraZeneca COVID-19 vaccine)
8. History of allergic reaction to aminoglycoside antibiotics
9. History of hereditary angioedema, acquired angioedema, or idiopathic angioedema
10. History of anaphylaxis in relation to vaccination

16. Individuals who have experienced thrombosis with thrombocytopenia syndrome (TTS) following vaccination with Vaxzevria (i.e. the Oxford/AstraZeneca COVID-19 vaccine)
17. Individuals who have previously experienced episodes of capillary leak syndrome
18. Severe and/or uncontrolled cardiovascular disease, respiratory disease, gastrointestinal disease, liver disease, renal disease, endocrine disorder, or neurological illness, as judged by the Investigator (note, mild/moderate well-controlled comorbidities are allowed)
19. Suspected or known current alcohol abuse as defined by an alcohol intake of greater than 42 units every week
20. Suspected or known injecting drug abuse in the 5 years preceding enrolment
21. Detectable circulating hepatitis B surface antigen (HBsAg)
22. Seropositive for hepatitis C virus (antibodies to HCV)
23. Any clinically significant finding on screening investigations, that are either unlikely to resolve or do not resolve on repeat testing (at the discretion of an Investigator) within the recruitment timeline of the study
24. 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 i
