SERUM ANTIBODIES TO THE PNEUMOCOCCAL SURFACE PROTEINS PhtB AND PhtE IN FINNISH INFANTS AND ADULTSHolmlund, Emma MSc*; Simell, Birgit PhD*; Jaakkola, Teija*; Lahdenkari, Mika MSc*; Hamel, Josée PhD†; Brodeur, Bernard PhD†; Kilpi, Terhi MD, PhD*; Käyhty, Helena PhD*Pediatric Infectious Disease Journal: May 2007 - Volume 26 - Issue 5 - pp 447-449 doi: 10.1097/01.inf.0000261198.90649.04 Brief Reports Abstract Author Information We examined naturally acquired antibodies to pneumococcal vaccine candidate proteins PhtB and PhtE in children during their first 2 years of life. Prior culture-confirmed pneumococcal exposure was shown to induce the development of anti-PhtB and -PhtE antibodies. The anti-PhtB or -PhtE antibody concentrations were not significantly associated with a decreased risk of subsequent pneumococcal acute otitis media.
