Abstract

Background

In 2015, Mongolia was among the earliest countries in Asia to introduce PCV. To monitor the impact of PCV13 introduction, we commenced nasopharyngeal carriage surveillance among children with pneumonia 6 months prior to vaccine introduction.

Methods

We recruited children 2-59 months of age presenting with pneumonia to district hospitals and the national Maternal and Child Health hospital in two districts in Ulaanbaatar. Clinical and demographic data, vaccination status and nasopharyngeal swabs were collected. A random sample of swabs were selected for testing each month. Samples were examined by lytA qPCR, with positives serotyped by microarray.

Results

We recruited 4980 children and tested 983 children from November 2015 to April 2018. The median age was 1.27 and 25.81% of cases were vaccinated in the first and second year following PCV13 introduction, respectively. 474 and 48.22% had received antibiotics in the 48 hours before admission.

Conclusions

Following PCV13 introduction in Mongolia, the prevalence of pneumococcal carriage remained stable while the prevalence of PCV13-type carriage decreased among children with pneumonia. Reductions in PCV13 carriage likely correspond to reductions in disease due to PCV13 types, since carriage is a precursor for disease.
