DTP vaccine (or DtaP, diphtheria, tetanus, pertussis)-DTP (or DtaP) injections are given as a series of five injections and usually at ages two months, four months, six months, 15-18 months, and four to six years of age.
For children, vaccination against tetanus is normally included in a vaccine called DTaP that protects against diphtheria, tetanus, and whooping cough (acellular pertussis).
The Diphtheria, Tetanus, and Pertussis (DTaP) vaccine is also administered to infants, and it once contained trace amounts of thimerosal.
At age 11 or 12, Td vaccine (tetanus and diphtheria) should be given if at least five years have elapsed since the last dose of DTaP.
The vaccine used in the United States is actually multiple diphtheria and tetanus toxoids combined with acellular pertussis (DTaP).
