DPT Vaccine

DPT Vaccine combines three vaccines, diphtheria, and tetanus toxoids, adsorbed with the pertussis vaccine. It protects you against three contagious diseases – Tetanus, Diphtheria, and Pertussis, which cause breathing difficulties and other complications if they are not appropriately treated. Generally found in the soil, the tetanus bacteria enter our body through abrasions, affecting the heart’s functioning.

Diphtheria Pertussis Tetanus Vaccine (DPT)

Vaccination is the first step to protect your child against illnesses that can be prevented by immunisation. Each dose of diphtheria, tetanus, and pertussis (DTwP) costs ₹225. The first dose of this vaccine is given once the child turns 6-weeks old.

Why is DPT Vaccine Given?

DPT vaccine is given for effective immunisation against diphtheria, tetanus and pertussis or whooping cough. All 3 can be fatal in children as they may lead to severe breathing difficulties and organ failure. DPT vaccine greatly reduces the possibility of contracting these diseases by making the body’s immune system resistant to these 3 bacteria. While DPT is usually administered to children, adults who want to boost their immunity can also get the vaccine.

How Effective is the DPT Vaccine?

DPT vaccine combines the weak toxins of diphtheria, tetanus and pertussis. They are chemically treated and made inactive. An inactive toxin is called a toxoid. A DPT booster mainly contains toxoids of all three diseases that trigger the body's immune response to develop resistance to these three diseases.

The effectiveness of DPT vaccines depends on the type of vaccine you opt for. DTaP vaccines are 80% to 90% effective. You must inoculate your kids with all 5 doses in time to reap maximum benefits. If vaccinated as per the schedule, 9 out of 10 children are fully protected. A complete DPT vaccine series offers 97% efficacy against diphtheria and 100% for tetanus.

How is DPT Vaccine Administered?

DPT is administered via an intramuscular injection. 3 doses are given at a 4-week gap, starting from 6 weeks of age. 2 additional booster shots are given at the age between 15-18 months and 5 years. Tdap is given at the age of 10 years and needs to be taken after every decade. DPT vaccine schedule should be adhered to for optimum results.

Types of DPT Vaccine

DPT vaccine comes in 3 types. They are:

  • DPwT

It contains the fully killed pertussis bacteria. Also referred to as the triple antigen vaccine, DtwP consists of tetanus and diphtheria toxoids and whole-cell pertussis bacilli, which are adsorbed on insoluble aluminium salts that play the role of adjuvants.

  • DPaT

It contains only trace proteins of pertussis germ. It has lower side-effects than DPwT but is equally effective. The vaccine also contains diphtheria and tetanus toxoid. Main pertussis toxins are tracheal cytotoxin (TCT), pertussis toxin (PT), and adenylate cyclase-hemolysin (AC-Hly).

  • Tdap

It contains weakened diphtheria toxic as well as pertussis trace. It's the least potent and effective among the 3 and is mainly administered to adults for boosting immunity with minimal side effects. According to the US CDC (Centre for Disease Control), Tdap should be given only to those who are older than 7 years of age.
