  1. Diphtheria immunity in flanders.

    Article - En anglais

    A serological survey to determine the immunity to diphtheria in the Flemish population was conducted according to the recommendations of the World Health Organization.

    Immunity to diphtheria was determined on a randomised, stratified sample (1679 serum samples) from an existing serum bank (4058 serum samples) representative of the Flemish population.

    All age groups between 0 and 100 years were included.

    A tissue (vero cell) culture toxin neutralisation assay was used to measure serum diph-theria antitoxin concentrations.

    The results showed that 43% of the Flemish population was protected against diphtheria (antitoxin titre, = 0.1 IU/ml), while 32% was susceptible (antitoxin titre,<0.01 lU/ml) ; for 25%, protection was of limited duration (antitoxin titre, =0.01 lU/ml and<0.1 lU/ml).

    The proportion of susceptible subjects showed a significant age-related increase, with the highest values in the 35 to 44 and 45 to 54 age groups (57.9% and 55.5%, respectively).

    These results emphasise the need for booster immunization of adults.
