Influenza Vaccine in HIV Infected Children

This study has been completed.

Influenza associated pneumonia causes significant morbidity in young HIV-infected children. Although annual vaccination against influenza is recommended for HIV infected children, it has not been implemented as routine care, due to the lack of data on disease burden and vaccine efficacy.

This study aims at determining the effectiveness of influenza vaccination in HIV infected children in South Africa.

Condition Intervention Phase
Influenza With Pneumonia, Influenza Virus Identified Biological: Trivalent sub-unit influenza vaccine Biological: Saline, 0.5ml Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Immunogenicity, Safety and Efficacy of Influenza Vaccine in HIV Infected Children

Further study details as provided by Michelle Groome, University of Witwatersrand, South Africa:

Primary Outcome Measures:
  • Determine the efficacy of a tri-valent influenza sub-unit vaccine, in HIV infected children with a CD4+ percentage >15% against vaccine-strain viral confirmed influenza illness. [ Time Frame: One year ]
  • Define the immunogenicity of influenza vaccination in a nested cohort of HIV infected children with CD4+ percentage >15% that are naïve to anti-retroviral or on antiretroviral therapy for more than 3 months [ Time Frame: One year ]

Secondary Outcome Measures:
  • Determine the safety of influenza vaccination in relation to solicited vaccine-related adverse events in the 72 hour period post-vaccination and any other unsolicited adverse event. [ Time Frame: One year ]
  • Compare the effect of the influenza vaccination on viral control and CD4+ cell count in HIV infected children six months following influenza vaccination. [ Time Frame: One year ]

Enrollment: 412
