Streptococcus pneumoniae (pneumococcus) is a common respiratory tract pathogen in children causing otitis media, sinusitis, bacteremia, and meningitis. Although comparatively rare, this pathogen can also cause early-onset neonatal sepsis (EONS) as well as late-onset neonatal sepsis and can mimic Group B streptococcal sepsis-like illness in neonates. S. pneumoniae can be transmitted vertically from maternal vaginal tract colonization or from the placenta through hematogenous spread. Two consecutive case reports of EONS are reported. Vaccination of the mother with pneumococcal polysaccharide vaccine during the third trimester may provide protection to infants by enhancing the transplacental transfer of active immunoglobulin (IgG) to the fetus, as well as improving the availability of secretory antibodies for the fetus through mother's milk. Immunization of the mother may also prevent genital colonization through resulting high levels of IgG plus mucosal CD17 lymphocytes.
