Vaccine failures in pediatric cases caused by streptococcus pneumoniae serotype 19A

Abstract

Community-acquired pneumonia (CAP) is a leading cause of childhood mortality and morbidity worldwide. PCV-13 has implemented incidence of CAP undoubtedly in a very good way but continuous surveillance for vaccine failures is still very important for future vaccination programs. To support this opinion we report seven children (age of the seven patients ranged between 10 months and 5 y, 10 months old patients were vaccinated 3 times with PCV13 whereas others were fully vaccinated as 3 + 1) infected with Streptococcus pneumoniae Serotype 19A in last 4 y (2015–2018).
