When should the tuberculosis vaccine be given?

Everyone knows the great harm of tuberculosis. Until today, there is no medical way to quickly cure tuberculosis. Therefore, once the disease occurs, healthy life will be greatly reduced, and even many obstacles will be encountered at work. Therefore, it is most important to take preventive measures for this disease. One preventive measure is to get a tuberculosis vaccine. So when is the most reasonable time to get the combined vaccine?

When should the tuberculosis vaccine be given?

Pulmonary tuberculosis is a relatively serious infectious disease. The period from infection with the bacteria to the onset of symptoms is called the incubation period of tuberculosis. Generally speaking, tuberculosis will develop within three months after infection, but it varies. Do you know how to treat pulmonary tuberculosis in children? On the basis of systemic therapy, we should fully mobilize the child's body's disease resistance and make the special anti-tuberculosis drugs better play an antibacterial role. We should pay attention to reasonable nutrition and rest, and choose foods rich in protein and vitamins, among which vitamins A and C are particularly important. Children should live in well-ventilated and sunny rooms. Children with severe tuberculosis have symptoms of poisoning such as fever and are extremely weak. They should stay in bed. Those with milder illnesses can do appropriate indoor and outdoor activities according to the specific situation. So when should children get the tuberculosis vaccine?

Normally born babies weighing more than 2500 grams can be vaccinated with BCG 24 hours after birth, and the vaccination should be completed before the age of 1 at the latest. If there is no source of infection at home, it is best to vaccinate premature babies with BCG six months after birth. However, if the baby's weight has exceeded 2,500 grams within six months and the doctor's examination shows that the baby's development is normal, the vaccine can also be given.

Adverse symptoms of vaccination:

Local redness, swelling, infiltration, suppuration and small ulcers will appear about 2 weeks after vaccination. If the condition is severe, appropriate treatment should be taken. The following reactions may occasionally occur during vaccination:

(1) Lymph node inflammation: About 1-2 months after vaccination, lymph nodes in the neck, armpits, and above and below the clavicle become enlarged (greater than 1.0 cm). In cases where the reaction is too strong, the lymph nodes will be obviously swollen, and abscesses or ulcers may form, or there may be small pus scars at the vaccination site. The reaction to intradermal injection is often stronger than that to the scratch method. In addition, those who have a positive old tuberculin (OT) test may also have a stronger reaction after vaccination.

(2) Lupus-like reaction: related to the residual virulence of the tuberculosis strain.

(3) Scars: Scars are formed due to abundant granulation tissue and sometimes appear as keloids. They are more common in those who receive direct skin scratch vaccination without undergoing OT testing.
