Why you need DPT vaccine?

What is DPT vaccine? DPT vaccine is a combination vaccine used for immunisation against Diptheria, Pertussis, and Tetanus. DPT vaccine protects your child (younger than age 7 ) and helps them to develop immunity against these deadly diseases. It also helps to reduce the reservoir of pertussis in the population at large and thereby potentially decreasing exposure of individuals at increased risk for complicated infection (e.g., infants). What is Diphtheria? Diphtheria is a localised infection of mucous membrane or the skin caused by Corynebacterium diphtheria. It is also suspected to be associated with the formation of pseudomembrane at the site of infection. Systemic effects are due to the production of the diphtheria toxin, a gene for present in specific corynephages. Occurrence It particularly affects children aged between 1-5 years. But a shift in age incidence has been observed from preschool to school age. People of higher age group may also contract diphtheria infection. What is Pertussis? Commonly known as whooping cough or the hundred day disease, pertussis is a highly contagious acute infection of the respiratory tract caused by Bordetella pertussis. It is clinically characterised by an insidious onset of mild fever and an irritating cough which gradually becomes paroxysmal with the characteristic inspiratory “whoop” (loud crowing inspiration). It is also associated with thick, tenacious salivation that often terminates in vomiting. What is Tetanus? Tetanus is a neurological disorder characterised by increased muscle tone and spasms, caused by tetanospasmin ( exotoxin liberated by Clostridium tetani). It occurs in several clinical forms, viz. Generalised, localised and neonatal tetanus. Despite the availability of effective vaccination since 1923, tetanus remains a major...
