Baby's redness and swelling after vaccination

In addition to checking all aspects of the baby's body after birth, regular vaccination is also very important. Because at this stage, if the child is not vaccinated in time, it is likely to cause some problems. There are many vaccines that need to be vaccinated in daily life. The most concerned is the diphtheria, pertussis and tetanus vaccination. However, a few people will experience local redness and swelling after vaccination. Here are some precautions about vaccination.

Time and method of DPT vaccination

Vaccination time: The first shot should be given when the baby is 3 months old. To complete the basic immunization of this vaccine, another shot should be given when the baby is 4 months and 5 months old. That is, antibodies against three infectious diseases: whooping cough, diphtheria and tetanus are produced in the baby's body.

Method of vaccination: Intramuscular injection is given in the upper 1/4 of the baby's buttocks or the deltoid muscle of the upper arm.

Reaction after vaccination: After the second injection of DTP vaccine, certain reactions often occur due to the increase in the injection dose. For example, the baby will cry and be restless, have difficulty falling asleep, and sometimes have a fever (generally not exceeding 38.5C) on the night after vaccination. The injection site will become red, swollen and painful, and may also make the baby irritable. This reaction usually lasts for 1 to 2 days before recovering on its own without requiring treatment.

Special reminder: If the baby's body temperature rises above 39.5C, and there are serious reactions such as convulsions, seizures, and continuous screaming, you should go to the hospital for diagnosis and treatment in time. When giving the third injection, the above situation should be reported to the doctor, who will decide whether to reduce the dose, switch to pertussis vaccine, or not give the third injection to avoid another serious reaction or allergic reaction.

What is the DPT vaccine?

DTP vaccine is the abbreviation of pertussis, diphtheria and tetanus combined vaccine. It is a mixture of three ingredients, including pertussis vaccine, refined diphtheria and tetanus toxoids. These three ingredients are mixed in appropriate proportions to obtain DTP vaccine. This vaccine is very effective in preventing whooping cough, diphtheria and tetanus. Currently used are adsorbed pertussis vaccine, diphtheria and tetanus toxoid mixed vaccine (adsorbed DTP) and adsorbed acellular pertussis vaccine, diphtheria and tetanus toxoid mixed vaccine (adsorbed acellular DTP).

Time for DPT vaccination

According to my country's current immunization program, newborns should start receiving the first dose of the diphtheria, pertussis and tetanus vaccine three months after birth, and receive three consecutive doses, with the shortest interval between each dose not less than 28 days. Then, they should receive a booster dose of the diphtheria, pertussis and tetanus vaccine when they are one and a half to two years old, and a booster dose of the refined diphtheria vaccine or the refined diphtheria-pertussis combined vaccine when they are seven years old. That is, antibodies against three infectious diseases: whooping cough, diphtheria and tetanus are produced in the baby's body.
