Impact of the National Vaccination Strategy on the Prevalence of <em>Streptococcus pneumoniae </em>and Its Serotypes Among Clinically Healthy Children Under Six Years of Age During and After the COVID-19 Pandemic

2025-05-06

Abstract excerpt

<h4>Background: </h4> An effective vaccination strategy requires monitoring serotype changes by geography and age. This study analyzed Streptococcus pneumoniae serotypes in healthy children under 6 years of age vaccinated with PCV10 in Bulgaria from October 2021 to May 2025. <h4>Methods:</h4> A total of 569 children were screened for the lytA and cpsA genes viаreal-time polymerase chain reaction (real-time PCR). P...
