  1. Immunity to hepatitis B, poliomyelitis and measles in fully vaccinated Aboriginal and Torres Strait Island children.

    Article - En anglais

    Objective 

    To determine the immunity to hepatitis B, poliomyelitis and measles in fully vaccinated Aboriginal and Torres Strait Island children in north Queensland.

    Methodology 

    A cross-sectional survey of immunity in a sample of children ; 101 fully vaccinated Aboriginal and Torres Strait Island children, with a median age of 24.5 months, from 10 communities in North Queensland participated in this study.

    The main outcome measures were the prevalence of adequate antibody levels against hepatitis B, poliomyelitis and measles.

    Results 

    Only 54% (95% Cl 44-63%) of the children had adequate immunity (=10 m iu/mL) to hepatitis B, and one child had been infected despite vaccination.

    Although all the children (95% Cl 96-100%) had adequate immunity (i.e. neutralizing antibodies at a dilution of =1 : 8) to poliovirus 2, only 93% (95% Cl 86-96%) and 60% (95% Cl 50-69%) had adequate immunity to polioviruses 1 and 3, respectively.

    Conclusions 

    Although a relatively low proportion of the children had adequate antibody levels against hepatitis B the clinical significance of this observation is uncertain.

    Further studies are needed to determine whether fully vaccinated Torres Strait Island children have been adequately protected and whether they require a booster dose of hepatitis B vaccine.

    A substantial proportion of fully vaccinated Aboriginal and Torres Strait Island children are inadequately protected against poliomyelitis.
