The use of topical and nasal glucocorticoids will be permitted;
* Participation in another clinical study involving study intervention within 4 weeks prior to the 1st study vaccination, or concurrent, planned participation in another clinical study with study intervention during the study period.
* Participants who are subjected to any global or local restrictions in place for use of ChAdOx1-S (e.g. age, gender, or other specific population groups)
* Investigators, or study staff who are directly involved in the conduct of this study or supervised by the investigator, and their respective family members.

<Stage2>
