DPT Immunization (Vaccine)

DPT (DTP) vaccination is one of the recommended childhood immunizations and should begin during infancy. In most parts of the United States, DPT immunization is required before starting school. A minimum of 3 injections should be given, and 5 injections is strongly recommended. DPT (DTP) immunization is usually a series of injections given to children at ages 2 months, 4 months, 6 months, and 15 to 18 months. A booster is given before starting school (age 4 to 6).
