Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this phase I first-in-human clinical trial, healthy volunteers in two different dose cohorts will be vaccinated twice with the candidate vaccine MVA-SARS-2-S. A subgroup will receive a heterologous booster vaccination with a licensed COVID-19 vaccine.

The aim of the study is to assess the safety and tolerability of the candidate vaccine and to characterize its immunogenicity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The vaccine contains a Modified Vaccinia Virus Ankara (MVA) vector expressing the SARS-CoV-2 spike protein (S). A total of 30 participants will receive the following vaccine regime:

15 participants will receive 10\^7 infectious units (IU) of MVA-SARS-2-S on days 0 and 28.

15 participants will receive 10\^8 IU of MVA-SARS-2-S on days 0 and 28. Safety and immunogenicity data will be collected throughout the study, which concludes at day 168.

A subgroup will receive a heterologous booster vaccination with a licensed COVID-19 vaccine. Vaccinees will receive two doses of the Comirnaty vaccine (21 days interval).
