medical dictionary

A vaccine consisting of diphtheria toxoid, tetanus toxoid, and pertussis vaccine. It is usually given to infants three times at two-month intervals, generally at 2, 4, and 6 months of age. The vaccine protects against diphtheria, tetanus, and whooping cough. In most cases the vaccine causes only a temporary fever and discomfort, but in a few cases serious neurological side effects have been observed.
