“…However, for AM specifically, PCV7 has not shown the same effect, and the incidence has remained stable or has in fact increased [56][57][58][59]. Halgrimson studied the incidence of AM in children younger than 2 years of age between 1999 and 2008; in 2001, before the widespread use of PCV7, the incidence was 11/100,000, in 2003, it dropped down to 4.5/100,000, and then it returned to 12/100,000 in 2008 [57].…”

“…Halgrimson reported that in his series P. pneumoniae was responsible for 30 % of the pathogens found in the pre-PCV7 and 50 % in the post-PCV7 era [57]. Navazo-Eguía et al reported that P. pneumoniae was isolated in 30 % of the cases in the pre-PCV7 era and in 42.1 % in the post-vaccination era [59]. An increase in bacterial resistance has been found in P. pneumoniae isolated in AM post-PCV7.…”

“…En América Latina y el Caribe existen reportes de 980.000 a 1.500.000 casos de OMA aproximadamente, para el año 2009 [15].
