The study is a multicenter study; the vaccine was administered in Germany along with the patients in the U.S. The study was intended to determine the safety, immunogenicity, and optimal dose level of four mRNA vaccine candidates. The company has considered two age cohorts for the study (18-55 and 65-85 years of age). The first phase is in patients of 18-55 years of age. Once the immunogenicity and safety get determined in the younger adults, doses will be given for older adults.
