Pneumococcus is the leading cause of bacterial illness in children worldwide. The development, clinical evaluation, and postlicensure impact of the pneumococcal CRM(197) protein conjugate vaccine, PCV13, (Prevnar 13®) builds upon the excellent safety and substantial effectiveness of PCV7 (Prevnar®) in preventing pneumococcal disease in children. PCV13 adds pneumococcal serotypes 1, 3, 5, 6A, 7F, and 19A to serotypes 4, 6B, 9V, 14, 18C, 19F, 23F in PCV7 to provide comprehensive coverage for over 85% of epidemiologically important pneumococcal serotypes in the United States and throughout the world. PCV13 development required demonstration of immunologic responses to the 13 serotypes contained in the vaccine that were noninferior to the responses elicited by PCV7, and demonstration of a satisfactory safety profile. Studies were also performed to demonstrate compatibility with other childhood vaccines. Now licensed in many countries worldwide, PCV13 shows significant promise for expanded protection against pneumococcal disease in children.
