What to do if your child gets redness and swelling after vaccination

Is it normal for children to have redness and swelling after vaccination? Many parents will have this problem. Many friends will find that their children’s arms are red and swollen after getting vaccinations. So what causes this? What are the dangers? Let’s take a look with the editor and see how we should deal with such problems.

It is normal for babies to experience redness, swelling, fever, hard injection sites, and anorexia after vaccination. These reactions will usually disappear naturally after two days. However, if the fever is over 38.5 degrees, measures should be taken (such as taking zinc taurate granules, one pack divided into three times) to ensure the healthy development of the baby's brain; if the fever is below 38.5 degrees, physical cooling can be adopted, such as wiping the body, taking a bath, drinking plenty of water, etc.; if there is redness, swelling, or hard and itchy needle wounds, dry ice wrapped in a hot towel can be used to bind the arms three times a day.

Local reactions: usually occur about 24 hours after vaccination. Redness, swelling, heat, and pain may occur at the injection site. Severe reactions can cause inflammation of nearby lymph nodes and lymphangiitis. The range of swelling and nodules at the injection site is divided into mild, moderate and severe. A mild reaction is one with a diameter of less than 2.5 to 5 cm, while a reaction larger than 5 cm is a severe reaction that can last for hours or days. 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. Systemic reaction: The first symptom is fever, with mild fever ranging from 37 degrees Celsius to 37.5 degrees Celsius and moderate fever ranging from 37.6 degrees Celsius to 38.5 degrees Celsius. Temperatures above 39 degrees Celsius are considered severe. In addition, some children may experience symptoms such as headache, dizziness, general weakness, chills, nausea, vomiting, abdominal pain, and diarrhea. The above reactions generally subside within 24 hours. Rarely lasts more than 3 years. If the fever is severe, you can take antipyretics. Generally, other symptoms will disappear on their own once the body temperature returns to normal. If the high fever persists or there are other abnormalities, the patient should be sent to the hospital for diagnosis and treatment in time.

Strengthen care after vaccination:

(1) Get enough rest and avoid running or jumping too much.

(2) Keep the injection site clean and do not scratch it with your hands. (3) Do not eat irritating foods, such as garlic, chili peppers, etc.

(4) Drink more water.
