Study Details

Study Description

Brief Summary

This study is part of an effort to develop an effective vaccination program in children in the event of a pandemic.

Study objectives:
  • To describe the safety profiles in the periods following each vaccination in subjects receiving different vaccination schedule.

  • To describe the immune response after each vaccination in subjects receiving study vaccine.

Condition or Disease Intervention/Treatment Phase
  • Biological: A/H5N1 Inactivated, Split Virion Pandemic Influenza Vaccine
Phase 2

Detailed Description

Study participants will receive two administrations of the investigational vaccine at one of 3 vaccination schedules.
