Pneumococcus carriage and antibiotic resistance in Malaysian children under 5

Official title: Nasopharyngeal Carriage, Serotype Distribution, and Antimicrobial Resistance Profile of Streptococcus Pneumoniae in Malaysian Children: A Prospective Multi-Centre Study

Run by IMU University, Malaysia · NCT07545876 · Data updated 2026-11-12

We'll test how often children under 5 in Malaysia carry pneumococcus in their nose, which serotypes they have, and whether those bacteria resist common antibiotics after the national vaccine rollout.

Is this trial a fit for you?

Likely a good fit

Healthy or mildly symptomatic children aged 0–60 months who have lived in Malaysia at least 3 months, are hemodynamically stable, have not used antibiotics in the past 30 days, and whose parent or guardian can give written consent.

Probably not a fit

Children who recently used antibiotics, have known immunodeficiency or recent chemotherapy/transplant, are on high‑dose steroids, have had nasal surgery, or live outside the recruitment areas are unlikely to be eligible or to benefit from this protocol.

What this trial studies

This observational cross-sectional effort will collect nasopharyngeal swabs from healthy and mildly symptomatic children aged 0–60 months at three urban and semi-urban centers in Kuala Lumpur, Selangor, and Negeri Sembilan. Samples will be cultured, serotyped, and subjected to antimicrobial susceptibility testing to determine carriage prevalence, circulating serotypes, and resistance patterns. Researchers will compare carriage rates and serotype/antibiotic-resistance profiles by age group and by vaccination history, including exposure to PCV10 and PCV13. The work aims to track serotype replacement and inform local vaccine and antibiotic policy decisions.

Why it matters

Potential benefit: If successful, the results could help tailor vaccine strategy and antibiotic guidelines to better prevent and treat pneumococcal disease in Malaysian children.

How similar studies have gone: Similar nasopharyngeal carriage and serotype surveillance studies worldwide have successfully tracked serotype shifts and antimicrobial resistance after PCV introduction, but post‑NIP data from Malaysia remain limited.
