Participant has a negative urine pregnancy test at Visit 7 prior to booster vaccination.~ 2. Participant agrees to employ adequate birth control measures up to 3 months after the Booster vaccination.~Exclusion criteria - Participants who meet ANY of the following criteria are NOT eligible for this study:~1. Clinically significant infection or other acute illness, including fever ≥ 38°C within 24 hours prior to the planned study vaccination.~2. History of laboratory-confirmed SARS-CoV-2 infection.~3. Participant had close contact to persons with confirmed SARS-CoV-2 infection within 30 days prior to screening (Visit 0).~4. Participant has participated in a clinical study involving an investigational SARS-CoV-2 vaccine.~5. Participant has an acute or recent infection not due to SARS-CoV-2~6. Participant has a history of SARS-CoV-1 or MERS infection (self-reported)~7. Participant tests positive for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV).~8. Participant has received any vaccine within 30 days prior Visit 1 other than the study intervention, with the exception of the seasonal influenza vaccination.~9. Participant has abnormal findings in any required study investigations (including medical history, physical examination, and clinical laboratory) considered clinically relevant by the Investigator.~10.

Participant has a known or suspected problem with alcohol or drug abuse as determined by the Investigator.~22. Participant has any condition that, in the opinion of the Investigator, may compromise the Participant's well-being, might interfere with evaluation of study endpoints, or would limit the Participant's ability to complete the study.~23. Participant is committed to an institution (by virtue of an order issued either by the judicial or the administrative authorities).~24. Participant has participated in another clinical study involving an investigational medicinal product (IMP) or device within 4 weeks prior to Visit 0 (screening) or is scheduled to participate in another clinical study involving an IMP, or device during the course of this study.~25. Participant is a member of the team conducting the study or in a dependent relationship with one of the study team members.~Exclusion Criteria for Booster Phase - Participants who meet ANY of the following criteria are NOT eligible for Booster phase:~* B1. Clinically significant infection or other acute illness, including fever ≥ 38°C within 48 hours prior to the planned Booster vaccination.~* B2. Participant has an acute or recent infection not due to SARS-CoV-2 and is not symptom-free in the week prior to the Booster vaccination (Visit 7).~* B3. Participant has received any vaccine within 30 days prior Visit 7, with the exception of the seasonal influenza vaccination.

Participant has a known or suspected problem with alcohol or drug abuse as determined by the Investigator.~* B10.
