Baby's arm is red and swollen after vaccination

Many children will develop some red, swollen and hard nodules on their arms after receiving vaccinations. This is the most common adverse reaction after vaccination. You can apply hot compresses with a hot towel several times, but it cannot be eliminated in just one or two times. If the redness and swelling are severe, you can go to the hospital to check whether there are signs of infection or allergy.

If your arm is red, swollen and has lumps, you can apply a hot towel to it a few times. It won’t go away in a moment, it will take time. If the redness and swelling are severe, you can go to the vaccination center (where you get the shot) and ask for some magnesium sulfate or magnesium sulfate. Use a hot towel soaked in water to apply a hot compress, and you will get better relatively quickly.

Introduction

It is an injectable vaccine. Vaccination is an effective means to prevent infectious diseases caused by certain pathogenic microorganisms (such as bacteria, rickettsia, viruses, etc.). Humans have used various vaccines to control the spread of diseases to the greatest extent possible. For example, the smallpox virus was basically eradicated after the emergence of the cowpox vaccine.

Depending on the type of vaccination, the injection site is different. Most common injections are on the arm, but there are exceptions such as on the buttocks and head.

1. If children who are suffering from a cold or fever caused by various diseases are vaccinated at this time, their body temperature will rise or the disease may be induced and aggravated.

2. Children who are recovering from an infectious disease or have a history of contact with acute infectious diseases but have not passed the quarantine period. If you get a vaccination at this time, it is easy to have adverse reactions or make the original condition worse.

3. Children with asthma, eczema, urticaria and allergic constitutions are prone to allergic reactions after vaccinations, especially measles vaccines, diphtheria, tetanus and pertussis mixed vaccines and other vaccinations with strong allergens, which are more likely to cause allergic reactions. Children with a history of epilepsy and convulsions are prone to syncope, convulsions, and shock when receiving vaccinations, especially Japanese encephalitis vaccine and diphtheria-tetanus-pertussis combined vaccine. People with severe rickets should not use polio sugar pills.

5. During the vaccination period, if the child is feeling uncomfortable, has symptoms such as vomiting, diarrhea, and severe cough, the vaccination can be temporarily postponed with the doctor's consent, and the vaccination can be given again after the symptoms improve.
