Antidiphtheria and antitetanus immunity in various age groups (0-70 yrs) in Romania

The evaluation of the antidiphtheria and antitetanus immunity level is still a topical question. The paper approaches the study of antidiphtheria and antitetanus immunity on age groups in 3,768 and, respectively, 4,001 subjects. In the studied population, the results of estimating immunity revealed an antidiphtheria percentage of 87.16% and a protection level against tetanus of 94.47%. The immunity level against both diphtheria and tetanus varied depending upon the studied age. The highest susceptibility values against diphtheria (29.42%) were recorded in the 6th decade and against tetanus (18.89-28.27%) in the 6th and, respectively, 7th decade. A high antidiphtheria and antitetanus immunity level (over 90%) was reported in children and young people after the IIIrd and IVth boosters).
