Primary Outcome Measures
NameTimeMethod
Occurrence of serious adverse eventsScreening up to week 34 after first vaccination

Occurrence, relationship to the trial vaccine and intensity of any serious adverse event (SAE).

Occurrence of grade 3 adverse eventsScreening up to week 8 after first vaccination

Occurrence of any grade 3 or higher adverse events possibly, probably or definitely related to the trial vaccine within four weeks after each vaccination.

Solicited local adverse eventsday of vaccination and the following seven days

Occurrence, intensity and duration of solicited local adverse events after each vaccination Occurrence, intensity and duration of solicited local adverse events after each vaccination Occurrence, intensity and duration of solicited local adverse events after each vaccination

Solicited general adverse eventsday of vaccination and the following seven days

Occurrence, relationship to the trial vaccine, intensity and duration of solicited general adverse events

Unsolicited non-serious adverse eventswithin four weeks after each vaccination

Occurrence, relationship to the trial vaccine and intensity of unsolicited non-serious adverse events

Secondary Outcome Measures
NameTimeMethod
RSV-specific humoral immune responsehumoral immune response is measured up to week 34

To assess the RSV-specific mucosal antibody responses by ELISA

Vaccinica-specific humoral immune responsehumoral immune response is measured up to week 34

To assess the Vaccinica-specific serum antibody responses by ELISA

Vaccinia-specific cellular immune responses.cellular immune response measured up to week 4 after 2nd vaccination

To assess the RSV-specific and vaccinia-specific cellular immune responses against the MVA-BN RSV vaccine in healthy adult subjects. Spot forming units will be determined by using an IFN-γ ELISPOT assay.
