What is DTP, how to get DTP vaccine, and what are the precautions? What should I do if I have a fever after vaccination? …then I will answer these questions for you one by one.

What is DTP vaccine?

DTP is used to prevent pertussis, diphtheria and tetanus, commonly known as DTP.

Pertussis: Pertussis is an acute respiratory infection caused by Bordetella pertussis. It is mainly transmitted through droplets and is extremely contagious; pneumonia and encephalitis can be complicated by it, and it is the main cause of infant death.  

Diphtheria: Diphtheria is an acute respiratory infectious disease caused by Gram-positive Corynebacterium diphtheriae; its clinical features are symptoms of poisoning caused by diphtheria bacillus exotoxin, and it is an infectious disease that poses a great threat to children’s health.  

Tetanus: Tetanus is a disease caused by tetanus bacteria infecting wounds. Tetanus bacillus invades the wound, causing neurological poisoning symptoms characterized by muscle rigidity and paroxysmal spasm, and finally death due to asphyxia and heart failure, with a high fatality rate. 

How to get the 100-day vaccine?

1. Adsorbed acellular DTP combined vaccine (immunization program vaccine)

Basic immunization: a total of three injections, starting from 3 months of age to 12 months of age, with an interval of 4-6 weeks between each injection. The booster immunization is usually performed within 18-24 months of age after the basic immunization.

2. Quadruple (non-immunization program vaccine)

For the prevention of pertussis, diphtheria, tetanus and invasive diseases caused by Haemophilus influenzae type b (including meningitis, pneumonia, upper respiratory tract infection, sepsis, cellulitis, arthritis, epiglottitis, etc.). Routine immunization program: basic immunization at 3, 4, and 5 months of age. Booster immunization for 18-24 months of age. With quadruple vaccination, the baby can get four fewer shots (Hib).

Three, quintuple (non-immunization program vaccine)

For the prevention of invasive infections (such as meningitis, sepsis, cellulitis, arthritis, epiglottitis, etc.) caused by diphtheria, tetanus, pertussis, poliomyelitis, and Haemophilus influenzae type b Three doses of basal immunization at 3, 4 months, or 3, 4, and 5 months; a booster dose at 18 months. Vaccination of the quintuple can make the baby less 8 shots of the vaccine (4 shots of polio + 4 shots of Hib).

What should I do if I have fever after the injection, and redness, swelling and induration at the injection site? 

1. Generally, a small number of children will have a fever reaction. The body temperature is below 38.5 ℃, physical cooling can be given, and warm water can be wiped. If the body temperature is above 38.5 ℃, symptomatic treatment should be given, and timely medical treatment should be given.  

If there is redness, swelling and induration at the injection site, this is a very common vaccination reaction in clinical practice. Family members do not need to worry too much. They can apply hot compresses to the local area, or cut fresh potatoes into thin slices and apply them to the red and swollen areas. Helps reduce swelling and pain and promote drug absorption.
