Arms and Interventions

ArmIntervention/Treatment
Experimental: Dose Escalation CVnCoV

Participants will be vaccinated with CVnCoV at escalating dose levels on Day 1 and Day 29.

Dose levels of 2, 4, 6, 8 and 12µg will be evaluated with potential increase to dose levels up to 20 μg.

Biological: CVnCoV Vaccine
Participants will receive an intramuscular injection by needle in the deltoid area.
Other Names:
  • CV07050101
  • Placebo Comparator: Dose Escalation Placebo

    Participants will be given placebo on Day 1 and Day 29.

    Drug: Placebo
    Participants will receive an intramuscular injection by needle in the deltoid area.
