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

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

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.

Study Overview

• Status: Completed
• Conditions: Influenza; HIV-1 Infection; Flu; H1N1
• Intervention / Treatment: Biological: FluMist; Biological: Fluvirin; Biological: Fluzone

Detailed 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.

• Genders Eligible for Study: All

• Sampling Method: Non-Probability Sample

Study Population

HIV-1 perinatally infected children and youth 6 months to 25 years of age.

For inclusion into the study, if perinatal acquisition of HIV infection cannot be confirmed based on the child's medical record, it is acceptable to enroll the child if the investigator's assessment is that the most likely route of infection was perinatal.

Description

Inclusion Criteria:

1. Children and youth 6 months to <25 years of age at study entry.

2. HIV infection, defined as positive test results obtained from 2 different samples. Tests may include two of the same type OR two different types of tests listed below, as long as there are positive test results obtained from 2 different samples:

   • HIV-1 antibody (ELISA + WB), obtained at age >18 months
   • HIV-1 culture, any age
   • HIV-1 DNA PCR, any age
   • HIV-1 RNA PCR >10,000 copies/mL, any age
   • Neutralizable HIV-1 p24 antigen obtained >28 days of age
3. In the opinion of the investigator, the route of HIV-1 transmission is perinatally acquired.
4. Parent or legal guardian, youth of legal age, or subjects who are emancipated minors, who are willing and able to provide signed informed consent.

5. Planned receipt of one of the following FDA licensed Influenza A (H1N1) 2009 Monovalent Vaccines within 24 hours following study entry:

   • Group A: Influenza A (H1N1) 2009 Monovalent Vaccine (MedImmune FluMist®)
   • Group B: Influenza A (H1N1) 2009 Monovalent Vaccine (Novartis Fluvirin®)
   • Group C: Influenza A (H1N1) 2009 Monovalent Vaccine (Sanofi Pasteur Fluzone®) *OR has received one of the above vaccines within 4 hours prior to study entry.

Exclusion Criteria:

1. Has a history of probable or proven pandemic 2009 H1N1 Influenza A virus infection prior to study entry.

3. Has received any 2009 H1N1 vaccines prior to the day of entry.
4. Has received any immunoglobulin or blood products within 3 months prior to study entry.
5. Has any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the study.
6. Use of anti-cancer chemotherapy or radiation therapy within the 36 months preceding study entry, or has immunosuppression as a result of an underlying illness or treatment (other than HIV-1 infection).
7. Has an active neoplastic disease.
