NCT01981967

Brief Summary

The aim of this study is to further characterize the safety profile of IMOJEV®. Primary Objective:

  • To describe serious adverse events (SAEs, including adverse events of special interest \[AESIs\]) up to 60 days after administration of one dose of IMOJEV®. Secondary Objective:
  • To describe Grade 3 (severe) systemic Adverse Events (AEs) up to 30 minutes after administration of one dose of IMOJEV®.
