    Didrik F Vestrheim
    Division of Infectious Disease Control, Norwegian Institute of Public Health, Nydalen, Oslo, Norway
    Vaccine 26:3277-81. 2008
    ..No vaccine failure was seen after complete primary immunization with two vaccine doses. Our findings indicate that PCV-7 provides highly effective protection against vaccine serotype IPD when administered in a 2+1 dose schedule...
  2. pmc Postvaccination increase in serotype 19A pneumococcal disease in Norway is driven by expansion of penicillin-susceptible strains of the ST199 complex
    Didrik F Vestrheim
    Department of Bacteriology and Immunology, Norwegian Institute of Public Health, Oslo, Norway
    Clin Vaccine Immunol 19:443-5. 2012
    ..Hence, serotype 19A replacement occurs, although it is not driven by antibiotic selection pressure...

    Didrik F Vestrheim
    Department of Bacteriology and Immunology, Norwegian Institute of Public Health, Oslo, Norway
    J Clin Microbiol 50:4114-5. 2012
    ..Growth was associated with a high bacterial load, as determined by PCR. Culture from PCR-positive samples is a feasible approach to recover B. pertussis isolates, and culture can be limited to samples with a high bacterial load...
  4. doi Indirect effect of conjugate pneumococcal vaccination in a 2+1 dose schedule
    Didrik F Vestrheim
    Division of Infectious Disease Control, Norwegian Institute of Public Health, NO 0403Oslo, Norway
    Vaccine 28:2214-21. 2010
    ..Among the adults aged > or = 65 years the incidence rate of IPD caused by serotypes not included in PCV7 increased. No vaccine failure was identified, indicating a very high effectiveness of the 2+1 dose schedule vaccination programme...
  5. doi Pherotypes of pneumococcal strains co-existing in healthy children

    Infect Genet Evol 11:1703-8. 2011
    ..3%). The observed distribution of pherotypes in sets of co-colonising pneumococcal strains did not differ from the probability estimate. Thus, co-colonisation of S. pneumoniae in healthy children is not restricted by pherotype...
  6. pmc Impact of a pneumococcal conjugate vaccination program on carriage among children in Norway
    Didrik F Vestrheim
    Department of Bacteriology and Immunology, Division of Infectious Disease Control, Norwegian Institute of Public Health, Nydalen, Oslo, Norway
    Clin Vaccine Immunol 17:325-34. 2010
    ..Direct and indirect protection of PCV7 against nasopharyngeal colonization was inferred from an overall decrease in carriage of PCV7 serotypes. No preference was found for nonsusceptible clones among the replacing non-PCV7 serotypes...

    Didrik F Vestrheim

    J Clin Microbiol 46:2508-18. 2008
    ..Our study indicates that carriage of S. pneumoniae is highly prevalent among children in Norwegian DCCs, with a genetically diverse pneumococcal population consisting of unique microepidemic DCC populations...

    Maria C Magnus
    Department of Chronic Diseases, Division of Epidemiology, Norwegian Institute of Public Health, Oslo, Norway
    Pediatr Infect Dis J 31:951-5. 2012
    ..A substantial effectiveness of PCV7 immunization against invasive pneumococcal disease has been demonstrated, whereas evidence of its impact on respiratory tract infections are less consistent...
