What Is a BCG Vaccination?

The main target of BCG vaccination is newborns, infants and young children. After vaccination, it can prevent tuberculosis in children, especially it can prevent and treat severe types of tuberculosis such as tuberculous meningitis. BCG vaccination is good for children's healthy growth.

BCG vaccination response

Subcutaneous or intramuscular injection is strictly prohibited.

Do not share the same syringe when inoculating BCG vaccine, to avoid increasing the hepatitis infection rate. Do not use if the ampoule is cracked or expired.

Do not inject on the same side when used with other vaccines.

The vaccine should be isolated from tuberculosis patients for 2 months after vaccination to prevent infection during this period. The tuberculin test will be performed after 2-3 months. The positive test indicates successful inoculation. The negative test should be replanted. After that, it should be replanted every 3-4 years. The tuberculin test should also be performed before replanting.

Immunization of patients with reduced immunity after chemotherapy will result in severe or even fatal infections. The interval between stopping chemotherapy and receiving live vaccines will be at least 3 months.

If scarring occurs after injection, do not remove it surgically during treatment. Local closed therapy can be used. Hydrocortisone acetate 12.5mg, isoniazid 100-300mg, 0.5% procaine solution are mixed properly, and then disinfected. The mixture was injected locally with a syringe twice a week, and after 10 consecutive times, the injection was stopped for 2 weeks, and then the injection was continued until the keloid became flat.

Local swelling and infiltration may occur in about 2 weeks after vaccination. If the pus subsequently develops and forms a small ulcer, it can be smeared with 1% gentian violet to prevent infection. Generally, it is crusted in 8-12 weeks. If local lymphadenopathy is encountered, it can be treated with hot compress. It has been softened to form a pustule, and the pus can be pumped with a sterile syringe; if it has been perforated, it can be treated with 10% sulfa ointment or 20% p-aminosalicylic acid ointment.

The product should be protected from light during use, and the live vaccine should not be exposed to sunlight during use.

Do not inject subcutaneously during intradermal immunization, otherwise it will cause severe deep abscess and will not heal for a long time. Excessive injection doses can cause abscesses or lymphadenitis at the vaccination site. Follow the recommended dose.

The inoculation object must register the name, sex, age, address, vaccine batch number and sub-batch number, manufacturing unit and inoculation date in detail.

The person who prepares the product should wear gloves, a mask and a gown. Containers, syringes, and other items that contain vaccines should not be used for other injections to prevent a purulent reaction. Related items should be disinfected before being discarded.

Freeze-dried injection vaccine dilution method: Use a sterilized 1mL syringe to accurately draw the diluted solution supplied with the product into the lyophilized BCG ampoule according to the required amount. After leaving it for 1 minute, shake the ampoule to dissolve it. Use the syringe to draw back and forth several times. To make it well mixed. Each ampoule must be used within half an hour from the time of dilution to prevent contamination.

[Just] People with tuberculosis, acute infectious diseases, heart, kidney, brain, and other diseases, extreme malnutrition, eczema, and other skin diseases are not allowed to be vaccinated. Before use, a tuberculin skin test must be performed, and those who are negative can be vaccinated.
