Trial overview

Official title: A phase IV, open-label, single-center study to evaluate long term immunogenicity up to 10 years after the first booster immunization with Tick Borne Encephalitis vaccine in adults who received 1 of 3 different primary vaccination schedules
Trial description: The aim of this study is to investigate the immunogenicity response in adults up to 10 years after one booster dose. Data collected from this study will allow for greater information to prescribers who administer TBE vaccine, so that they can appropriately time the administration of booster vaccinations to individuals who received different vaccination schedules and who live in tick borne encephalitis endemic regions.
Primary purpose:
Prevention
Trial design:
Single Group Assignment
Masking:
None (Open Label)
Allocation:
Not applicable
