  1. Diphtheria antitoxin levels in the 14-30-year age group in Italy.

    Article - En anglais

    In order to verify diphtheria immunity a seroepidemiological survey was performed in 1996-1997.

    Serum samples were obtained from 501 subjects 14 years old, recruited at 8 schools in Rome, and from 490 subjects 20-30 years old recruited from 15 Italian regions.

    Serum diphtheria antitoxin was titrated using the Vero cell assay.

    The minimum protection level of antitoxin was set at 0.01 IU ml-1.

    The results show that the younger population have a good immunity to diphtheria while a large proportion of young adults is devoid of protective levels of diphtheria antitoxin.

    Out of the 501 subjects 14 years old.

    495 (98.8%) had a diphtheria antitoxin titre >= 0.01 IU ml-1.

    Only 6 (1.2%) teenagers were susceptible.

    Out of the 490 subjects 20-30 years old, 109 (22.2%) were susceptible. 381 (77.8%) had a diphtheria antitoxin titre >= 0.01 IU ml-1.

    The data stress for booster immunization at the end of junior high school.
