Why don t I have a flower on my arm, that is, I haven t been vaccinated against tuberculosis?

The injection was unsuccessful or not injected, or the scar was not visible after the successful injection. The most effective way to prevent tuberculosis is to inject BCG vaccines.

Bacillus calmette-guérin (abbreviated as BCG, the Chinese name comes from its inventor Bacillus calmette-guérin) is a vaccine used to prevent tuberculosis, made from live, non-virulent Mycobacterium bovis. Immunity to Mycobacterium tuberculosis is developed after inoculation with the human body by causing a mild infection. More than 90% of the recipients will form ulcers at the site of inoculation for several weeks to six months, and finally heal to form scars, commonly known as stuck scars.

Mycobacterium bovis loses its pathogenicity to humans after several years of passage on a special artificial medium, but still maintains a high enough immunogenicity to become a vaccine that can prevent tuberculosis to a certain extent, and is effective in preventing tuberculous meningitis and hematogenous disseminated tuberculosis.

That's right, in fact, the skin test is to give you a very small amount of a certain vaccine (the vaccine is actually a kind of germ-like thing) to see if your reaction can adapt. If the skin test shows that you don't have a swollen bag, it means that your body can accept it, then you can be vaccinated; If you are like this, it means that your body cannot accept it (maybe you are sensitive or your immune system is relatively poor, or maybe you are allergic to this kind of thing), and if you force it, you may have a fever or even be life-threatening.

Hello, there is nothing wrong with this, under normal circumstances, the preventive vaccine for children is once every 30 days. Children who have been vaccinated with the same equipment should be given proper rest, do not do strenuous exercise, do not eat irritating foods such as chili peppers, and do not take a bath for the time being. As long as you take good care of it and feed it with more boiling water, it will be fine in no time.

In rare cases, children may have a high fever and can be seen by a doctor for symptomatic treatment.

When I was just born, I generally took two vaccines - BCG and the first shot of hepatitis B vaccine, of which BCG is a live vaccine, which is made after artificial treatment with Mycobacterium tuberculosis bovis, and there will be mild redness, pain, fever and confusion and even lymphadenopathy and pain in the armpit on the injection side, which is considered normal, as long as it is not too bad, you don't need to deal with it, if you don't worry, you can go to the hospital to ask, but after eight months, there should be no more redness, swelling, pain, One of the conditions such as fever; As for the hepatitis B vaccine, he was made by Shinho with hepatitis B surface antigen, which is a dead vaccine, and there will be a small keloid at the injection site at 8 months, as long as there is no pain, fever, etc., it is normal. If you don't feel safe, you can go to the hospital and ask, there should be no problem. It is recommended that other vaccinations should be taken on time, and that vaccination records should be kept because it will be used in many situations such as when children go to school or go abroad, so it is very important.

As you said, in this case, the child vaccinated with Benzotan should be BCG, only a few people can have pimples, or suppuration, it is not good to last for so long, it is still relatively rare, you still go to the hospital to see what the situation is, it is difficult to understand it very clearly on the Internet. It's not as good as a face-to-face consultation I hope it helps.

To have a certain period of time, you need to go to the epidemic prevention station from the new species.

This requires the help of professionals, go to the hospital for consultation and the safest, and the child's affairs should not be sloppy.

BCG is a vaccine used to prevent tuberculosis in children. Vaccination can give children a special resistance to tuberculosis. At present, most countries in the world have listed BCG as one of the vaccines that must be vaccinated for immunization.

BCG vaccination is mainly given to newborn infants and young children, and it can prevent the development of tuberculosis in children, especially those severe types of tuberculosis, such as tuberculous meningitis. BCG vaccination is good for the healthy development of children. BCG vaccination is called the "first shot at birth", so newborn babies should be vaccinated at birth in maternity hospitals and obstetric departments.

About 2 weeks after inoculation, local redness, swelling, infiltration, suppuration, and the formation of small ulcers appeared.

BCG is inoculated on the left arm, the upper edge of the deltoid muscle, intradermal injection within 24 hours to 1 month of birth, the purpose is to prevent tuberculosis, and there will be a package just after vaccination.

The smallpox vaccine, commonly known as cowpox, is no longer vaccinated because the smallpox virus was eradicated in 1978.

The flowers you are referring to are actually cowpox... Used to prevent smallpox... Smallpox has long since been eradicated.
