What should I do if my baby becomes red and swollen after vaccination?

After the baby is born, he begins to develop continuously, and the child's physique is relatively weak. Babies are more susceptible to viral and bacterial infections, so they should be given vaccinations when they are very young, hoping to eliminate some diseases through prevention. However, some babies have allergic constitutions. Let’s learn what to do if the baby becomes red and swollen after vaccination.

Although the probability of abnormal reactions such as redness, swelling or fever after vaccination in infants is extremely low, and even very rare, it should still be taken seriously. If it occurs and requires special treatment and serious conditions, timely treatment is required. After vaccination with diphtheria, pertussis and tetanus vaccine or hepatitis B vaccine containing adsorbents, local nodules may appear. If the nodules are small and mild, they will be naturally absorbed gradually.

Some babies may experience redness and swelling after vaccination. If the local redness and swelling are severe, you can apply hot compress (hot compress is strictly prohibited for redness and swelling after BCG vaccination). Once in the morning and once in the evening, each time for about 5 minutes. And you should change your underwear frequently to avoid infection after ulceration. If there is local infection, apply gentian violet solution.

Generally, on the second day after the injection, that is, after the needle hole is closed, hot compress should be applied 3-4 times a day, each time for 15-20 minutes. Parents of young children are reminded to pay attention to the moderate temperature of the hot compress and not to measure it based on the temperature sense of adults.

Some children may also have fever. When the body temperature does not exceed 38.5℃, no intervention is required. Just let the child drink more water. If the body temperature exceeds 38.5℃, he or she needs to take an antipyretic drug once. But it should be noted that it is an antipyretic drug for children that does not contain aspirin. Generally, one dose is enough.

If your baby becomes red and swollen after receiving a vaccination, it may be due to some infection of the baby. Some babies may have an allergic constitution, which may cause redness and swelling. When this happens, stop taking the medication. Do not continue using it to avoid causing more serious consequences and reactions.
