The role of DPT in infants

Children can be said to be the hope of the entire family. Every parent hopes that their children can grow up healthy and happy. We know that babies will go to the hospital regularly for vaccinations after birth to avoid the occurrence of some diseases. Among them, the baby will be injected with diphtheria, pertussis and tetanus vaccine in the third month after birth. However, many parents do not fully understand its role and do not realize the importance of vaccines. Let’s take a look at the role of diphtheria, pertussis and tetanus vaccines for babies.

The role of DPT in infants

Years of practice at home and abroad have proven that the DTP vaccine has a good preventive effect on whooping cough, diphtheria and tetanus. It is generally believed that the immunization effect against tetanus and diphtheria is more satisfactory.

The DTP vaccine is the best choice for preventing tetanus. After basic immunization with diphtheria, pertussis and tetanus vaccine or two doses of tetanus vaccine, the antitoxin in all vaccinated sera can reach above the protective level, the antibodies can be maintained for 10-15 years, and the protection rate can reach more than 95%.

The preventive effect on diphtheria is also ideal. After basic immunization with DTP vaccine or two doses of diphtheria vaccine, about 90% of people can reach a protective level of diphtheria antitoxin in their serum. If a booster shot is given at 1.5 to 2 years old, the antibodies can last for more than 5 years.

There has been controversy over the effectiveness of the DTP vaccine in preventing whooping cough. However, according to some reports, one month after completing the basic immunization with diphtheria, pertussis and tetanus vaccine, the agglutinin antibodies in the serum can increase by more than 20 times compared with before immunization, and the protection rate can reach about 80%. Another booster shot should be given at 1.5-2 years of age, and the antibodies can last for at least 2-3 years.

The above is an introduction to the effects of DTP vaccination for infants. After understanding it, we know that DTP vaccination for infants can effectively prevent diseases such as tetanus and diphtheria. Therefore, parents must take their babies to get vaccinated regularly when taking care of their babies. However, it is worth noting that once the baby has a fever, vaccination should be avoided, and bathing is prohibited after vaccination.
