Diphtheria toxoid combined with tetanus and pertussis vaccines (DTP) has been part of the WHO Expanded Programme on Immunization (EPI) since its inception in 1974.

DTP3 coverage is often used as a proxy indicator to measure the performance for the immunization system.

Diphtheria vaccinations are given in routine immunization services in the Western Pacific Region. The disease is caused by the bacterium corynebacterium diphtheriae. This bacterium produces a toxin that can harm or destroy human body tissues and organs. Another type, more common in the Tropics, causes ulcers on the skin.

Pertussis (commonly known as whooping cough) is a highly contagious bacterial disease of the respiratory tract. It occurs mainly in infants and young children, and is easily transmitted from person to person, mainly through droplets. The first symptoms generally appear 7-10 days after infection, and include mild fever, runny nose, and cough, which in typical cases gradually develops into a paroxysmal cough followed by a whooping noise. Pertussis can be prevented by immunization.
