BCG vaccination precautions

Children have to get various vaccinations from birth, which shows how much attention their families pay to their children. Vaccinations should be given every month or quarter from the time the child is born to around 5 years old. The most common vaccines are hepatitis B vaccine, vaccine against tuberculosis, etc. When a child is born, beans are planted on the child's hands to prevent him from getting rashes. Although vaccinations are painful for children, they are necessary.

Nowadays, many children are given BCG vaccination. BCG is specially processed. It is a vaccine made from living tuberculosis bacteria without viruses. This vaccine is particularly effective in preventing diseases in humans. So what precautions should be taken for BCG vaccination? Is it harmful to the human body?

The reaction after BCG vaccination is different from that of general vaccinations. Usually about 3 weeks after vaccination, redness and swelling will appear at the vaccination site, gradually softening in the middle and forming small white pustules. After the pustules rupture, pus will be discharged, and it will take 1-2 weeks for a scab to form. After healing, a round scar may remain. The above process generally lasts about 2 months. After vaccination with BCG, the lymph nodes near the vaccination site (mostly the axillary lymph nodes) will often swell. This is a normal reaction. As the vaccination site heals, the swollen lymph nodes will disappear on their own. Hot compresses can be used to promote its disappearance. If an abscess is formed, you can ask the doctor to use a syringe to extract the pus to promote healing. It generally does not affect the child's health.

BCG vaccination is safe, but for the sake of caution, vaccination should be contraindicated for patients with immunodeficiency diseases, immunosuppression caused by malignant diseases such as tumors and leukemia, and those treated with immunosuppressants such as corticosteroids. Vaccination should be postponed or carried out with caution for children in the following conditions.

1. Newborns who are born prematurely, have difficult labor, or have obvious congenital malformations.

2. Children with acute infectious diseases such as fever and diarrhea.

3. Patients with chronic diseases of the heart, lung, kidney, severe skin diseases, allergic skin diseases, nervous system diseases, and those who have allergic reactions to vaccinations.

Therefore, when getting the BCG vaccine, do not randomly choose a hospital for vaccination. First of all, you must find out clearly whether this hospital is a regular epidemic prevention department. If you get the vaccine without knowing it clearly, it will cause great harm to your child. Therefore, for the safety of your children, parents must understand the situation of the hospital before getting the BCG vaccine to see if they are a regular vaccination department. Parents are advised to be cautious for the health of their children.
