At least 24 hours after the baby is born, as long as it is healthy, the hospital will vaccinate the baby on the upper left arm of the BCG vaccine. #BCG’s role is to reduce the number of tuberculosis bacteria in the body after vaccination, thereby reducing the incidence of primary tuberculosis, blood-borne disseminated tuberculosis and tuberculous meningitis in children, but it cannot completely prevent tuberculosis infection. Normal reaction after vaccination · A light red induration will appear within 2 to 3 weeks after inoculation; · A hard shell will form around the red induration around 4 to 6 weeks after inoculation,  . . . . . . .  . . Intermediate softening, forming a pustule, with a diameter of no more than 1 cm; · About 6 weeks after inoculation, the pustule ruptures, forming a skin lesion with a diameter of approximately 5 mm; · The skin lesion generally heals within 3 months and leaves a permanent scar. Care after vaccination · When pustules form at the vaccination site, remember not to squeeze, do not grasp with hands, change underwear frequently, and keep local dryness; · After the pustule is ruptured, as long as the wound is kept clean, alcohol and iodine can not be used If you have already used alcohol and other disinfected ulcers, re-test the PPD skin test 3 to 4 months after inoculation; · You can take a bath at any time after inoculation, without using sterile gauze or waterproof stickers to isolate the inoculation site. Dry the inoculation site. If the abscess diameter exceeds 1 cm or the abscess does not heal for more than 3 months, you need to see a doctor.
This article applies to newborn babies. What is the BCG vaccine skin test? The BCG vaccine skin test is a tool for diagnosing tuberculosis. It generally refers to the tuberculin test, also known as the Mantu test and the PPD test. Through this test, we can judge the human tuberculosis infection and provide a basis for vaccination. When the tuberculin test is positive, it means that the body has been infected with tuberculosis bacteria, and there is no need to inoculate BCG. Only those who show negative are BCG vaccination targets. . In addition, the BCG skin test is also a test that needs to be done when the BCG vaccine is reviewed. After 3 months of vaccination, the baby should have a BCG skin test to check whether the BCG vaccine has immunity in the body. If the tuberculin is positive, it means that the BCG vaccine is inoculated. If successful, the BCG vaccination needs to be repeated. & nbsp. BCG vaccine skin test is necessary to do & nbsp. BCG vaccine skin test is necessary to do, especially in newborns who have been vaccinated with BCG vaccine, after 3 months of vaccination, the BCG vaccine skin test should be done because In order to detect whether the vaccination is successful, whether the body has immunity or not, this is a very important basis. If the test result shows that the vaccination failed, then it needs to be re-vaccinated, so that the baby can be protected from tuberculosis and other infestations. BCG vaccine skin test reaction & nbsp. BCG vaccine skin test response is an important basis for vaccination with BCG vaccine, so close observation is generally required to detect the reaction within 48-96 hours. BCG vaccine skin test response is generally localized induration, the main test The method is to observe the horizontal and vertical diameter of the induration. In addition to induration, the possible reactions are blisters, necrosis, or lymphadenitis. These are the reactions that may occur after the BCG skin test. The doctor will make a conclusion based on these reactions. & nbsp. BCG vaccine skin test results & nbsp. BCG vaccine skin test results are mainly to see whether there is induration and induration size, the site of injection of PPD is only needle-sized traces, and no induration, it is a negative reaction, indicating that BCG vaccine has no Effectiveness, at this time, further examination is needed to determine whether it is related to the baby’s insufficient immune function, or to the technical operation of the BCG vaccination process; if the site appears red and swollen, and there are indules with a diameter of about 5-10 mm, it is a positive reaction. This shows that the BCG vaccine has been successfully vaccinated and has developed resistance to tuberculosis bacteria in the body. There is also a case where the induration diameter exceeds 20 mm, or there is redness, blisters and necrosis on the induration, accompanied by lymphatic counties. This is a strong positive reaction and should go to the hospital for further examination. & nbsp. BCG positive skin test is what is happening & nbsp. BCG positive skin test is only indicative of tuberculosis infection, when it does not necessarily mean disease. If the newborn’s test is positive before the BCG vaccination, it means that the newly infected active tuberculosis should be treated. However, the BCG skin test is generally carried out after 3 months of BCG vaccination. If it shows positive, it means that the BCG vaccine has been successfully vaccinated and has developed resistance to tuberculosis in the body. & nbsp. & nbsp. * The content of this article comes from the Internet, only for sharing.
