Laboratory Study of Licensed H1N1 Influenza Vaccines in HIV-1 Perinatally Infected Children and Youth

Influenza Clinical Trial

Official title:
A Laboratory Study to Assess the Immunogenicity of Three Licensed Influenza A (H1N1) 2009 Monovalent Vaccines in HIV-1 Perinatally Infected Children and Youth

Clinical Trial Summary

The purpose of this research study is to evaluate the immune response to the H1N1 influenza or "flu" vaccine. The "immune response" is how your body recognizes and defends itself against bacteria, viruses, and substances that may be harmful to the body.

HIV-1 infected children typically respond more poorly to vaccines compared to uninfected, healthy children and so this study hopes to learn whether or not the body will successfully produce enough antibodies (proteins that fight infection) that will prevent or fight the H1N1 flu virus. There is no information yet on the safety or immune response to this vaccine in children infected with HIV.

Clinical Trial Description

HIV-infected children typically respond poorer to vaccines as compared to normal children. The FDA has currently approved several Influenza A 2009 monovalent vaccines to be used in children and adults. However, little data is available in perinatally infected youth. Therefore, knowledge of the immunogenicity of several of the licensed Influenza A 2009 monovalent vaccines in HIV-infected children and youth is critically important to address the health care needs of this vulnerable population. Efforts are currently underway to evaluate Influenza A 2009 monovalent vaccines in healthy children as well as other populations. This study will assess the immune response following receipt of three Influenza A monovalent vaccines in HIV-1 infected children and youth. Protection of HIV-1 infected children and youth from 2009 H1N1 Influenza A will require knowledge of immunogenicity of these new products in this population. The 2009 (H1N1) Influenza A virus is likely to infect a significant proportion of HIV-1 infected children and youth. Immunogenicity of licensed and commercially available Influenza A 2009 monovalent vaccines must be established in HIV-1 infected children in order to assure that this population is protected. Lack of a protective immune response would support the need for additional measures to protect this high risk population. ;
