Generally, infants can be inoculated with BCG vaccine within 24 hours after birth, and redness, swelling and caking may appear 2-3 weeks after inoculation. During this period, small white pustules may gradually form, ulcers will appear after self-rupture, and circular scars will appear after scarring and shedding. Therefore, the induration caused by BCG in newborns is a normal vaccine reaction, and there is no need for mothers to be too nervous when they see this situation.
After BCG injection, the reaction will be different from that of general vaccination. After this kind of vaccination, most children will have local redness and pus. After the pustule is broken, it will scab after a while. After healing, it will leave a permanent scar, which may accompany the child's life, especially the baby with scar constitution. Once a scar is formed, it is difficult to get rid of it.
In a word, the induration caused by BCG is normal, but the swelling, induration and pustule at the inoculation site will gradually scab and fall off, and you can't dig it during the period. The scab skin formed needs to wait for it to fall off slowly, while keeping the inoculation site clean and dry to avoid bacterial infection.

At the same time, parents should also correctly treat some adverse reactions caused by BCG vaccination.
Because the child has immunosuppression, there may be a big pimple on his arm after BCG vaccination. He may feel a little itchy when the big pimple subsides. In the meantime, try not to let children scratch with their hands, otherwise inflammation and infection will easily occur. If the big pimple on the arm is seriously infected locally, it is best to go to the hospital to see a doctor.

BCG becomes a picture of a red pimple protruding. Is it normal to grow red pimples after BCG?
Once a child suffers from tuberculosis, it will do great harm to his body. In order to prevent the occurrence of tuberculosis in children, it is very necessary to vaccinate BCG. Children can produce anti-tuberculosis bacteria after being vaccinated with BCG, which has become a necessary vaccine in China's planned immunization. Moreover, the baby vaccinated with BCG will be partially red and swollen, eventually forming a small scar. So what is the picture of BCG turning into a red pimple? Is it normal to grow red pimples after BCG?
Some babies get red pimples after BCG vaccination, as shown below. This situation is a vaccine side effect caused by the baby's immune mechanism, which has a certain relationship with the baby's physique and will not cause any harm to the body. Generally, babies will get BCG after birth. After BCG vaccination, there will be local redness and swelling, and some babies will have red pimples. This is a normal vaccine reaction. Generally aseptic suppuration does not require treatment. It will slowly absorb and form a scar.
Generally, after BCG vaccination, the baby's arm will not be red and swollen in a large area, and the redness is not particularly obvious, so don't worry too much. However, if there is suppuration at the inoculation site, pus should be squeezed out to keep the wound dry and hygienic, which is conducive to the early recovery of the wound. Usually, you can let your baby drink more warm water, promote blood circulation and substance metabolism, and improve the phenomenon of red pimples.
In short, most babies will have some reactions after BCG vaccination. At this time, parents don't have to worry. As long as the adverse reactions are not particularly serious, they are all normal reactions. In the meantime, we should continue to observe. If the reaction to the vaccine thickness is still serious, go to the hospital in time.
BCG normal scar map, BCG scar will disappear?
China is also a country with high incidence of tuberculosis. Failure to take effective measures to prevent tuberculosis in time will definitely increase the number of people infected with tuberculosis, so BCG has become one of the free vaccines. However, after BCG injection, there will be some adverse reactions, such as local redness, fever, drowsiness and so on. What is the normal scar map of BCG? Will BCG scar disappear?
The scar left after BCG vaccination is actually a side effect of this vaccination. Generally, scars will form 2-3 months after BCG vaccination, but the baby's arm after BCG vaccination will appear local redness and pus before scars appear. These conditions are normal after vaccination, and parents of babies don't have to worry.
Why are there scars after successful BCG vaccination? In fact, after the baby was injected with BCG, some skin functions were destroyed by bacteria. At this time, the body will start the immune cells, and the immune cells will have BCG scars after interacting with the inoculated BCG. Once the BCG scar is formed, it will hardly disappear, but it may gradually fade or even be invisible as the baby grows older. Babies with scar constitution may be accompanied by scars left by BCG vaccination for a lifetime.
The scar formed after BCG vaccination can also be used as a sign to judge whether the vaccine is successful, but not every child will form a scar after BCG vaccination. Studies have shown that about 10% of children will not have card marks after BCG vaccination, which is normal. If parents are worried that there is no BCG antibody in the baby, they can go to the hospital for testing, so that they can more accurately judge whether the baby needs BCG vaccination.
