Acute otitis media (AOM), one of the most common childhood diseases, is associated with a substantial medical, social and economic burden. Non-typeable Haemophilus influenzae (NTHi) and Streptococcus pneumoniae are the two main causes of bacterial OM. The 7-valent pneumococcal CRM197-conjugate vaccine (7vCRM, Prevnar (TM)/Prevenar (TM), Wyeth) demonstrated efficacy against AOM caused by vaccine pneumococcal serotypes. Protection against overall AOM was also observed with an 11-valent pneumococcal protein D-conjugate vaccine (11Pn-PD) in the Pneumococcal Otitis EfficacyTrial (POET). Following POET, an optimized 10-valent pneumococcal non-typeable H. influenzae protein D-conjugate vaccine (PHiD-CV; Synflorix (TM), GlaxoSmithlKline Biologicals) was developed. This vaccine includes serotypes 1, 5, and 7F, in addition to those already included in 7vCRM, and was recently licensed in Europe for active immunization against invasive disease and AOM caused by S. pneumoniae in infants and children from 6 weeks up to 2 years of age. The use of protein D as carrier protein permits avoidance of possible interferences known to occur with some conjugate vaccines, and has the added potential benefit of providing protection against NTHi. This review seeks to highlight the recent advances in the field of OM vaccination, with a focus on data regarding the recently licensed PHiD-CV. (C) 2009 Published by Elsevier Ltd.
