A consensus or society position rather than new primary data.
This narrative mini-review identifies three high-risk paediatric populations (malnutrition, measles, malaria) in low- and middle-income countries with elevated pneumococcal disease burden and immune dysfunction, and proposes targeted PCV strategies including catch-up vaccination, booster dosing, and post-infection vaccination. However, the review highlights that specific PCV recommendations for these groups remain lacking and identifies research priorities rather than reporting new clinical evidence.
Journal article. High-risk children under five years of age in low- and middle-income countries, specifically those with malnutrition (stunting or wasting), and those following measles or malaria infection; also under-vaccinated children with limited access to PCV..
Pneumococcus remains the leading cause of pneumonia, accounting for an estimated 28% of approximately 500,000 deaths among children under five years of age Risk of death from pneumonia was approximately 2 times greater among moderately underweight children and 5 times greater among severely underweight children compared with normal weight children Severe acute malnutrition (SAM) was associated with 9.2-fold (95% CI 4.8–46) increased odds of pneumonia mortality in a prospective cohort study in Uganda
Severe acute malnutrition (SAM) was associated with 9.2-fold (95% CI 4.8–46) increased odds of pneumonia mortality in a prospective cohort study in Uganda
Clinicians and public health professionals in LMICs should recognize that standard PCV schedules may be insufficient for high-risk groups and that targeted strategies—catch-up vaccination, booster doses in high-risk periods, and post-infection vaccination—warrant investigation. However, this review does not establish specific recommendations; it identifies evidence gaps and research priorities that must be filled before such strategies can be widely implemented.
This mini-review synthesizes evidence on disease burden and immune vulnerability in high-risk child populations to inform targeted PCV strategies, but contains no new primary data or comparative trials.

Streptococcus pneumoniae remains a leading cause of pneumonia mortality among children under five years of age, with the greatest burden in low- and middle-income countries (LMICs). Children with malnutrition and those following infection with measles or malaria experience immune dysfunction, with subsequent high risk of severe pneumonia and death. Targeted pneumococcal conjugate vaccine (PCV) strategies, timed to periods of greatest vulnerability among these high-risk groups, could reduce pneumonia burden and mortality in LMICs yet research in these populations remains limited, and specific PCV recommendations are lacking. This mini-review summarizes the disease burden and immune vulnerability associated with malnutrition, measles, and malaria, and highlights key research priorities to inform targeted PCV strategies among these high-risk children.
