A seroprevalence study of tetanus and diphtheria was carried out in a sample of 537 health care workers in Catalonia. The prevalence of protective antibodies against tetanus was 93.9% (95% confidence interval: 91.5-95.7). The prevalence of protective antibodies against diphtheria was 46.4% (95% confidence interval: 42.1-50.7). Tetanus protection should be improved in health care workers born before 1975. The immune status against diphtheria was poor, with less than half of people born before 1975 correctly immunized.
