Inclusion criteria
Healthy male and female participants ≥18 years of age. A healthy participant is defined as an individual who is in good general health, according to the Investigator's assessment. Chronic health conditions are acceptable if the condition is considered well controlled with treatment according to the discretion of the Investigator.
Expected to be compliant with protocol procedures and available for clinical follow-up through the last planned visit.
Participants are able to understand and willing to provide informed consent.
Physical examination without clinically significant findings according to the Investigator's assessment.
Body mass index (BMI) ≥18.0 and ≤32.0 kg/m^2.
Female participants of childbearing potential: at the time of enrollment, negative human chorionic gonadotropin (hCG) pregnancy test (serum) for female participants presumed to be of childbearing potential on the day of enrollment. On Day 1 (pre-vaccination): negative urine pregnancy test (required if serum pregnancy test was performed more than 3 days before).
Female participants of childbearing potential must use highly effective methods of birth control from 2 weeks before the first administration of the trial vaccine until 3 months following the last administration. The following methods of birth control are considered highly effective when used consistently and correctly:
Male participants should be instructed not to get their partners pregnant until 3 months after the last administration.
Exclusion criteria
Use of any investigational or non-registered product (vaccine or drug) other than the trial vaccine within 28 days preceding the administration of the trial vaccine, or planned use during the trial period.
Receipt of any other vaccines within 28 days prior to enrollment in this trial or planned receipt of any vaccine within 28 days of trial vaccine administration (primary dose or booster dose).
Receipt of any investigational or licensed/authorized SARS-CoV-2 or other coronavirus vaccine prior to the administration of the trial vaccine.
Any treatment with immunosuppressants or other immune-modifying drugs (including, but not limited to, corticosteroids, biologicals, and methotrexate) within 6 months prior to the administration of the trial vaccine or planned use during the trial, with the exception of topically-applied, inhaled, or intranasal steroids.
Use of hormonal therapy for gender reassignment.
Any medically diagnosed or suspected immunosuppressive or immunodeficient condition based on medical history and physical examination, including known human immunodeficiency virus infection, hepatitis B virus infection, and hepatitis C virus infection.
History of immune-mediated or autoimmune disease.
History of angioedema (known C1 inhibitor deficiency).
History of anaphylaxis or allergy to any component of CVnCoV or aminoglycoside antibiotics.
History of or current alcohol and/or drug abuse.
Participants who are active smokers, were active smokers within the last year (including any vaping in the last year), or have a total smoking history ≥10 pack years. A pack year is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years the person has smoked.
History of virologically-confirmed Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), or COVID-19 disease or known exposure (without any personal protective equipment) to an individual with confirmed COVID-19 disease or SARS-CoV-2 infection within the past 2 weeks.
Administration of immunoglobulins and/or any blood products within the 3 months preceding the administration of any dose of the trial vaccine.
Presence or evidence of significant uncontrolled acute or chronic medical or psychiatric illness. Significant medical or psychiatric illnesses include but are not limited to:
Foreseeable non-compliance with protocol, as judged by the Investigator.
For female participants: pregnancy or lactation.
Participants with impaired coagulation or any bleeding disorder in whom an intramuscular injection or a blood draw is contraindicated. This includes participants on treatment with anticoagulants (e.g., vitamin K antagonists, novel oral anticoagulants, and heparin). Use of platelet aggregation inhibitors is not exclusionary.
Participants employed by the Sponsor, Investigator, or trial site, or relatives of research staff working on this trial.
Participants considered at the Investigator's discretion to be at increased risk of exposure to COVID-19 disease.
