Insights
Vaccine coverage in children with HIV is suboptimal, particularly for vaccines administered in primary care. Oral polio vaccine was safe, but overall immunization rates require improvement to prevent future illness.
Area of Science:
- Pediatrics
- Immunology
- Infectious Diseases
Background:
- Highly active antiretroviral therapy has improved outcomes for children with HIV.
- Vaccine response in HIV-infected children is crucial for preventing morbidity and mortality.
- Assessing current vaccination status in this population is essential.
Purpose of the Study:
- To determine vaccine coverage in HIV-infected children and adolescents.
- To evaluate vaccine safety and adherence to recommendations.
- To compare vaccine uptake between primary care and hospital settings.
Main Methods:
- Retrospective review of medical records for 68 HIV-infected children and adolescents.
- Analysis of coverage for specific vaccines including oral polio vaccine (OPV), hepatitis B virus (HBV), varicella, pneumococcal, meningococcal, and influenza vaccines.
- Assessment of vaccine safety and concordance with recommendations.
Main Results:
- Suboptimal vaccine coverage was observed overall.
- Oral polio vaccine (OPV) coverage was 44%; only 9.1% received a second HBV series due to low response.
- Varicella vaccination was low (14.7%), while pneumococcal (23-valent: 82.3%, 7-valent: 100%) and meningococcal (80.8%) coverages were higher. Influenza vaccination was poor (22.7%).
- Vaccine uptake was lower for immunizations administered in primary care compared to hospitals.
- OPV administration was safe with no adverse effects.
Conclusions:
- Vaccine coverage in HIV-infected children is suboptimal.
- Immunization rates are lower for vaccines given in primary care settings.
- Targeted interventions are needed to improve vaccination rates in this vulnerable population.
Abstract:
Since the implementation of highly active antiretroviral therapy in HIV-infected children, response to scheduled vaccines may determinate future morbidity and mortality. The aims of this study have been to describe the current vaccine coverage, vaccine safety and concordance with vaccine recommendations of the 68 HIV-infected children and adolescents followed up in our Unit. Forty-four percent of the children received at least one dose of the oral polio vaccine (OPV). Only 9.1% needed and received a second set of hepatitis B virus immunization because of low vaccine response. Only 14.7% were vaccinated against varicella. Coverages of 82.3% and 100% have been reached with the 23-valent and the 7-valent pneumococcal vaccines, respectively. Meningococcal conjugated vaccine uptake was moderate (80.8%). Influenza annual vaccination coverage was poor: only 22.7% had well-documented yearly vaccines. In our experience, vaccine coverage is lower in those vaccines administered in primary care centres compared with the immunizations given at the hospital. OPV administration did not cause any adverse effect in the children or in their families. Vaccine coverage in HIV-infected children was suboptimal.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
