Brief Summary:
The objective is to assess immunogenicity of a commercial IC51 batch at 3 different time points post filling (12, 18, 24 months) in terms of Geometric Mean Titers (GMT) for anti-JEV neutralizing antibodies at Day 56 after the first vaccination.

Condition or disease Intervention/treatment Phase
Japanese Encephalitis Biological: IC51 Phase 3

Detailed Description:

Open-label, multicenter, phase 3 study assessing immunogenicity at various time points throughout the shelf-life of a commercial batch of IC51 (Batch IC51/07F/008) The study population consists of male and female healthy subjects, aged at least 18 years.

The study will be performed at 3 study centers in Germany and Austria. Three sequential cohorts, each containing 100 subjects, will be enrolled into the study at approximately 12, 18 and 24 months after filling of the commercial batch IC51/07F/008 of IC51
