What is the cause of fever after leprosy vaccination?

After the child is born, he or she needs to go to the hospital for vaccinations every once in a while for the sake of the baby's health. Although the quality of vaccines on the market varies, in order for babies to grow healthily, vaccines cannot be discontinued under any circumstances. Leprosy vaccine is also one of the vaccines that babies must receive, but the baby developed a fever after the vaccination. Is this normal?

Many mothers reported that their babies’ immunity decreased and they were prone to fever after receiving the leprosy vaccine. Why?

A low fever after a child receives the leprosy vaccine is a normal immune response, not a decrease in resistance as most people misunderstand. In fact, the low fever shows from one side that the child has a better response to the vaccine. Parents only need to strengthen care and observation and do not need to worry too much. The Ministry of Health stipulates that fever after vaccination must be at least above 38.5℃ to be reported to superiors.

How to care for babies who have various adverse reactions after vaccination?

First of all, the most common adverse reaction is low-grade fever. Parents need to pay close attention to their children's temperature changes and the condition of the vaccination site. Generally speaking, if the body temperature does not exceed a low fever of 38.5℃, and general reactions such as redness, swelling, and nodules at the injection site occur, no treatment is required. Remember not to take any measures at will. Secondly, if you experience a high fever or a large nodule at the vaccination site, seek medical attention promptly and report to the vaccinating doctor. The treatment of reactions caused by different vaccines is not exactly the same. For example, hot compress can be applied to the nodules caused by vaccination with diphtheria, pertussis and tetanus vaccine, but hot compress is strictly prohibited for nodules caused by vaccination with BCG. So if you find any abnormal situation, remember not to deal with it arbitrarily.

Is it unacceptable for mothers to delay vaccination?

Of course not! Vaccines refer to preventive biological products used for human vaccination in order to prevent and control the occurrence and spread of infectious diseases. The fundamental purpose of vaccination is to prevent infectious diseases. Of course, some vaccines may cause adverse reactions in children, such as low fever, rash, crying due to fright, etc., but in most cases, these adverse reactions are normal and transient. Parents must not delay the normal vaccination procedure because of fear. The national immunization program is formulated based on the characteristics of the vaccine, the developmental status of children, and the epidemic patterns of the disease. As long as the child has no contraindications to the corresponding vaccine, it is best to vaccinate the child in a timely manner to reduce the risk of infection.

Of course, if your child has special conditions such as fever or cough on the scheduled vaccination date, the vaccination date should be postponed accordingly. This postponement of vaccination does not affect the protective effect of the vaccine, but it should be given in time to reduce the risk of infection.

Spring is the season when various infectious diseases are prevalent, especially respiratory diseases such as measles, rubella, and influenza. Parents need to be vigilant. In addition to taking their children to get vaccinated on time, they should also pay attention to avoid taking their children to crowded public places with poor environments to prevent their children from contracting diseases. You should drink plenty of water and wash your hands and change your outer clothes when you get home from outside.
