Abstract
Background: Pediatric infectious diseases pose a significant risk to child health worldwide. Vaccination programs have greatly reduced the incidence and severity of these diseases, though coverage and efficacy differ across regions. This mini-review examines how effectively these programs reduce pediatric infectious diseases by analyzing existing literature on vaccine impact in various countries.
Methodology: A literature search across PubMed, MEDLINE, ScienceDirect, and CINAHL (Dec 2017 - May 2022) used specific MeSH terms, including ‘pediatric vaccination,’ ‘disease incidence,’ and ‘vaccine efficacy.’ Out of 928 articles initially retrieved, 48 underwent full-text screening, and seven met the final criteria.
Results: The review highlights significant reductions in pediatric infectious diseases, particularly in regions with high vaccination coverage for diseases such as pneumococcal pneumonia, measles, and Hib (Haemophilus influenzae type b). Studies report over 90% reductions in incidence rates for certain diseases in countries with comprehensive immunization programs, showcasing the importance of sustained, widespread coverage. Conversely, in regions with lower coverage, diseases remain prevalent, indicating the need for strengthened immunization strategies.
Conclusion: Effective vaccination programs are crucial for reducing pediatric disease rates, improving public health, and fostering herd immunity. Increased vaccine accessibility, education, and coverage are necessary, especially in low-coverage regions, to advance global health goals for pediatric control.
