    Clin Vaccine Immunol 19:96-9. 2012
    ..Higher anti-serotype 14 and anti-serotype 19F IgG and anti-serotype 14 IgM correlated with a lowered probability of pneumococcal acquisition. Postvaccination OPA did not correlate with pneumococcal carriage...

    Birgit Simell
    Department of Vaccines, National Public Health Institute, Helsinki, Finland

    Birgit Simell
    National Institute for Health and Welfare, Helsinki, Finland
    Vaccine 27:4615-21. 2009
