Nasopharyngeal carriage studies provide insights into the local prevalence of circulating pneumococcal serotypes. These data are critical to vaccination monitoring, as they allow for prediction and assessment impact. Very little available on serotypes in Morocco. Here, we describe Streptococcus pneumoniae serotype distribution among 697 pediatric patients with ages ranging from 2 59 months who were admitted a Moroccan hospital severe pneumonia, well 195 healthy infants young children recruited at clinic. Carriage rates 40.5% (79/195) 22.8% (159/697) sick children. The most commonly observed included 6A, 6B 19F, all which current 13-valent anti-pneumococcal conjugate vaccine that was recently introduced Monitoring remains necessary after introduction assess whether replacement is occurring.
