Document Type


Publication Date



Objective: To review the immunogenicity, efficacy, and safety of the 13-valent pneumococcal conjugate vaccine (PCV13) for use in pediatric patients. Data Sources: A MEDLINE search (2000-September 2011) was conducted using the key words Streptococcus pneumoniae and pneumococcal conjugate vaccine for clinical trials, limited to studies conducted in humans and published in English. Study Selection And Data Extraction: Randomized, controlled, multicenter trials were reviewed and included to evaluate the safety and efficacy of PCV13. Literature on the epidemiology and pathology of pneumococcal infections and recommendations from the Advisory Committee on Immunization Practices (ACIP) were also reviewed. Data Synthesis: PCV13 is approved for routine vaccination of all infants as a 4- dose series at age 2, 4, 6, and 12-15 months for children who previously received 1 or more doses of the 7-valent pneumococcal conjugate vaccine (PCV7), and for children with underlying medical conditions that increase their risk for pneumococcal disease or its complications. PCV13 has comparable immunogenicity to the serotypes common with PCV7 and also provides protection against 6 additional pneumococcal serotypes. PCV13 has also been shown to have a comparable adverse reaction profile to PCV7. Conclusions: Based on published immunogenicity and safety data, as well as the recent recommendations by the ACIP for routine use in infants and indications for high-risk pediatric patients, PCV13 is a revised formulation of pneumococcal vaccine that should be included on pharmacy formularies.
