In 2017, a multi-dose vial presentation (4-dose vial) has been made available on the market at a reduced cost per dose. In 2010, Benin, with the support of The Global Alliance for Vaccines and Immunizations (GAVI), introduced the single-dose PCV13 vaccine in its EPI Program. The vaccine has been strongly recommended for young children, and adults at high risk of acquiring pneumococcal infections. PCV13 is a pneumococcal conjugate vaccine providing protection against 13 serotypes of pneumococci. The fight against pneumococcal infections includes vaccination which has been recognized as the most cost-effective strategy for reducing pneumococcal-related morbidity and mortality. In addition, global statistics of under-five mortality indicated that a high proportion was due to pneumococcal infections. Furthermore, pneumococcal meningitis-related sequelae, including deafness, blindness and intellectual deficit, can be very serious, even disabling. Mortality from severe pneumococcal infections is also important since 9 to 19% of Sp meningitis diagnosed in health facilities succumb to the infection. Severe pneumococcal infections is also relatively important in children less than 5 years, with 18% of all severe pneumonia infections caused by S. Streptococcus pneumoniae is one of the leading causes of severe pneumonia in adults, and bacterial meningitis in children less than 1 year.
