Context
The pneumococcal conjugate vaccine (PCV), although available since the year 2000, has only recently been introduced in low-income countries. It is therefore important to focus on the serotypes circulating in children under 5 years old, as part of a pneumococcal vaccination program.
This study aims to establish a central protocol to generate high quality and specificity serotype prevalence data that allow the study of the transmission pattern and the direct or indirect impact of PCV, in Cambodia.
