Safety and Immunogenicity of an Intramuscular A/H5N1 Inactivated, Split Virion Pandemic Influenza Vaccine in Children
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 |
