Comparison of Vaccination Routes: Subcutaneous Versus Intramuscular Application of FSME-Immun®
May 16, 2018 updated by: Univ. Prof. Dr. Ursula Wiedermann, Medical University of Vienna
FSME-Immun® is registered for application into the muscle.
This study investigates if application under the skin leads to a comparable immune response.

Detailed Description
Tick-borne encephalitis (TBE) vaccine (FSME-Immun®) is registered for intra-muscular application.
Due to medical reasons (e.g.
anticoagulant therapy, adipositas) intra-muscular application is not always possible.
The aim of this clinical trial is to investigate whether a comparably good immunogenicity can be achieved via the subcutaneous vaccination route.
Thus humoral and cellular immune responses after intramuscular and subcutaneous TBE vaccination in healthy volunteers will be compared.
