What are the adverse reactions to the chickenpox vaccine?

Varicella is a highly contagious viral disease that has caused a large number of deaths in human history and is known as a terrible disease. With the advancement of modern medical technology, people have invented the varicella vaccine injection method for prevention, which has greatly reduced the incidence of varicella and increased the overall life expectancy of humans. Although the varicella vaccine is effective, it also has a certain risk of adverse reactions. Let's take a look at the adverse reactions after the varicella vaccine.

1. Fever or symptoms of general discomfort such as nausea, vomiting, diarrhea, etc. After the injection of varicella vaccine, remember to observe the child's body temperature. The bedroom temperature must be maintained at 37-38 degrees Celsius. If there are symptoms such as nausea, vomiting, abdominal pain, diarrhea, general fatigue, general discomfort, etc., they usually appear within 1-2 days after vaccination and will disappear on their own within 1-2 days. If the child's temperature exceeds 38.5 degrees, antipyretics should be given under the guidance of a doctor.

2 Allergic reactions such as redness, swelling, tenderness, and nodules may occur in the local area where the varicella vaccine was injected. Redness, swelling, and some pain will appear 12-24 hours after the vaccination, and will disappear on their own after 2-3 days. For individual severe cases, hot compress treatment can be used after the acute period. Do not scratch with your hands. Gently touch and massage are fine. Be sure to keep the injection site clean.

3. Dizziness, irritability and other abnormal reactions. After receiving the varicella vaccine, you may experience dizziness, irritability, pale face, numbness of hands and feet, sweating all over the body, etc. within a few minutes. In this case, let the child lie down and rest immediately to restore to normal. In severe cases, emergency treatment must be given under the guidance of a doctor. Such symptoms must be related to the child's physical constitution and only occur in very few children. It can be seen from this that although the varicella vaccine can effectively prevent varicella, it should be noted that you should first understand its side effects before the injection. When adverse reactions occur, timely treatment should be sought to avoid worsening of the disease.

4. Precautions for varicella vaccination: After vaccination, you should press the needle hole with a cotton swab for a few minutes. Remove the cotton swab only when there is no bleeding. Do not rub the vaccination site.
