Insights
Pneumonia and diarrhea remain leading infectious killers of young children globally, particularly in low-resource regions. Continued progress requires funding existing vaccines and developing new ones against common childhood pathogens.
Area of Science:
- Global child health
- Infectious disease epidemiology
- Vaccinology
Background:
- Pneumonia and diarrhea are the top infectious causes of mortality in children under five worldwide.
- These deaths disproportionately affect low- and middle-income countries (LMICs) in sub-Saharan Africa and Southern Asia.
- Significant reductions in child mortality have been achieved through public health interventions and vaccines.
Purpose of the Study:
- To highlight the ongoing burden of pneumonia and diarrhea in young children globally.
- To emphasize the role of existing vaccines in reducing child mortality.
- To advocate for continued investment in vaccine programs and new vaccine development.
Main Methods:
- This study is a review of global child mortality trends.
- It analyzes the impact of public health interventions and vaccination programs.
- It discusses future needs for vaccine development and implementation.
Main Results:
- Child mortality has decreased globally over the past decade.
- Vaccines against Streptococcus pneumoniae, Haemophilus influenzae, and rotavirus have contributed to these reductions in LMICs.
- Further reductions are contingent on sustained funding and new vaccine development.
Conclusions:
- Despite progress, pneumonia and diarrhea remain critical threats to child survival in LMICs.
- Expanding access to current vaccines is essential.
- Investment in novel vaccines targeting prevalent pathogens is crucial for future gains.
Abstract:
Pneumonia and diarrhea are the 2 leading infectious causes of death in children younger than 5 years worldwide, most of which occur in low- and middle-income countries (LMICs) in sub-Saharan Africa and Southern Asia. The past decade has seen large reductions in global childhood mortality, partly due to expansion of nonspecific public health interventions and vaccines against Streptococcus pneumoniae, Haemophilus influenzae, and rotavirus in LMICs. Further progress in this field depends on the international community's commitment to fund and implement programs using currently available vaccines and development of new vaccines against pathogens common to children in LMICs.
