Brief Summary:

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.


Condition or disease Intervention/treatment Phase
Covid19 Biological: MVA-SARS-2-S vaccinations (days 0 & 28) Biological: Comirnaty Phase 1

Detailed Description:

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).

Primary Outcome Measures :
  1. Percentage of Participants Experiencing Solicited Local or Systemic Reactogenicity as Defined by the Study Protocol [ Time Frame: during the entire study (up to 6 months) ]
    Safety and reactogenicity will be assessed by observation, questionaire and diary. Occurence of Serious Adverse Events (SAE) will be collected throughout the entire study duration.


Secondary Outcome Measures :
  1. Immunogenicity. Number of participants who seroconverted [ Time Frame: during the entire study (up to 6 months) ]
    Magnitude of SARS-CoV2-specific antibody responses (ELISA and neutralization assays) monitored in an approved laboratory
