Clinical Trial Summary

This will be a phase I, single-center trial, including a total of 30 participants in two cohorts. Cohort 1 (n=6): Healthy male or female adults aged 18 - ≤ 60 previously primary immunized with two vaccinations with any regimen using any EU marketed SARS-CoV-2 vaccine (mRNA-, vector-, protein-based, attenuated SARS-CoV-2 virus) or with a single application of COVID-19 Vaccine Janssen. Cohort 2 (n=24): Healthy male or female adults aged 18 - ≤ 60 primary immunized with two vaccinations with any regimen using any EU marketed SARS-CoV-2 vaccine (mRNA-, vector-, protein-based, attenuated SARS-CoV-2 virus) or with a single application of COVID-19 Vaccine Janssen and subsequently booster immunized with any EU marketed mRNA vaccine Both cohorts will be assigned to inhaled vaccination with MVA-SARS-2-ST
