Diphtheria, pertussis, and tetanus are serious diseases caused by bacteria. The DPT or DTaP vaccines are given to children to prevent these diseases. They contain inactivated toxins (toxoids) for diphtheria and tetanus and acellular pertussis components.

Vaccination Schedule

DTaP is administered to children at 2 months, 4 months, 6 months, 15-18 months, and 4-6 years. DPT is used in countries where the acellular pertussis vaccine is not available, and the schedule may vary.

Diphtheria

Diphtheria is a serious bacterial infection that usually affects the mucous membranes of the nose and throat, causing a thick covering in the affected area. It can lead to difficulty breathing, heart failure, paralysis, and even death.

Pertussis

Pertussis, also known as whooping cough, is a highly contagious respiratory disease. It is known for uncontrollable, violent coughing which often makes it hard to breathe. After fits of many coughs, someone with pertussis often needs to take deep breaths which result in a "whooping" sound.

Tetanus

Tetanus (lockjaw) is a serious disease that causes painful muscle tightening and stiffness, usually all over the body. It can lead to the tightening of muscles in the head and neck, so the victim cannot open their mouth or swallow, or sometimes even breathe.

Side Effects and Safety

DTaP and DPT vaccines are safe. However, as with any medicine, they can have side effects. These are usually mild, such as fever, redness or swelling at the injection site, and fussiness. Serious side effects are rare but can include severe allergic reactions.
