When it comes to vaccines, many parents have the following question: After the child is vaccinated, he has a fever and a rash. Don't vaccines prevent disease? Why does my child get sick after being vaccinated? This condition is mostly caused by adverse reactions after vaccination. So, what are the side effects of the vaccine after the child is vaccinated? How to deal with it?

Fever

After vaccination, some children may experience fever, headache, fatigue, irritability, loss of appetite, etc. Among them, low-grade fever is the most common and usually lasts for 1 ~2 days. When the child has a low fever, the body temperature does not exceed 38.5 ℃, and there are no other symptoms, parents should not worry too much, strengthen observation, pay attention to keeping the room ventilated, and replenish water to the baby in time (the baby within 6 months of breastfeeding a small amount of times), You can also physically cool down by wiping with a towel, fanning, etc., while ensuring the child's rest time.

Local redness and swelling

If the child has local redness, swelling, pain, induration, etc. at the vaccination site, it usually subsides gradually after 24 to 48 hours.

Second-rate. If the diameter is ≥3cm, seek medical attention as soon as possible, and inform the doctor of the type of vaccine and the time of vaccination for the child as soon as possible.

The whole process will last for 2 to 4 months. When nursing, just wipe it with water and then dry it. Do not use alcohol, iodine, disinfectant, etc. for local disinfection, so as not to affect the vaccine effect and delay the wound healing time.

Diarrhea

Some children experience abdominal discomfort and mild diarrhea after being vaccinated.

However, the probability of such adverse reactions is extremely low, and once it occurs, it is necessary to go to a regular hospital for diagnosis and treatment as soon as possible. Generally speaking, if the diagnosis and treatment are timely, it will not cause too much damage to the child's body.

Coupling infection

If the child happens to be in the incubation period of a certain disease, or the child happens to have a contraindication for vaccination stipulated in the vaccine instructions, after vaccination, the child's original The acute relapse of the disease or the emergence of a new condition, such adverse reactions are coupled infections. To prevent coupled infection, parents need to do two things.
