13-valent pneumococcal conjugate vaccine in Africa

This is the authors' abstract. We don't add key points for this paper.

Pneumococcus is the leading cause of bacterial infections in human beings and is a major source of mortality and morbidity worldwide. The incidence of pneumococcal diseases in children varies among populations and countries, and differences have been attributed to several factors, including overcrowding, poverty, underlying conditions (such as HIV infection), and genetics. Accumulation of many of these factors in low-income and middle-income countries, particularly those in Africa, accounts for why a large amount of the global burden of pneumococcal diseases and most of the related deaths are in these countries.
