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.
If a patient with a history of fevers and febrile convulsions is to be given DTP, the patient should receive acetaminophen at the time of the injection and for the following 24 hours.
Although there have been warnings about severe, even fatal reactions to DTP vaccine, these reactions were seen in about one in 140,000 cases with whole cell DTP.
Also, immunosuppressant drugs, including steroids and cancer drugs, may reduce the ability of the body to produce antibodies in response to DTP vaccine.
Several vaccines are delivered in one injection, such as the measles-mumps-rubella (MMR) and diphtheria-tetanus-pertussis (DTP) combinations.
