Study Design: A 15 month surveillance study of Nasopharyngeal Carriage and Antibiotic Resistance of S. pneumoniae in Healthy Jordanian Infants will be launched in Jordan (Ajlun) in the time period between May 2009 to August 2010. Children will be given the 7vPCV as during the 3rd, 5th and 10th months of age (two plus one scheme). Nasopharyngeal swabs will be collected from the DCCs of Ajlun. Questionnaires and special forms will be taken with each isolate and will be sent to the reference lab at the German-Jordanian University for isolation of pneumococci, identification, serotyping, and resistance and for molecular analysis, statistical analysis and coverage. Agreement from the Ministry of Health (MOH), to take all ethical points regarding sample collection into consideration will be guaranteed. The samples will be cultivated at a microbiology lab of the German-Jordanian University. Molecular methods will be investigated in Germany at the National Reference Center for Streptococci. Phases of project implementation will be collection of the samples, and identification.
