- Furthermore, Serotyping of S. pneumoniae isolates of all pneumococcal strains isolated in this study would give an idea about the coverage of the vaccine available and would answer the families question shall we vaccinate our children or not!! Why should we pay 85 JDs privately to vaccine since the coverage is less than 50% as an example. Here comes the question whether we should use the 13 va,lent vaccine of the same type, which is still under development. Carriage of S. pneumoniae in Jordan pediatrics below 5 was developed in the primary results of the carriage in Jordan and was 57%. if the carriage distribution in the Jordanian population has to do with specific serotypes, which are included in the 7-vPCV, then vaccination would be the best idea to prevent occurrence of the infection then decrease morbidity and later the mortality rate due to the infections of this pathogen. The northern of Jordan constitutes of more than 50% of all non-meningococcal infections.
