Tuberculosis usually refers to tuberculosis, and it is possible to get a tuberculosis vaccine if you have a tuberculosis patient in your family. TB is a highly contagious disease caused by infection with Mycobacterium tuberculosis. When there is a TB patient in the family, the infection can be spread through the respiratory tract, the patient’s saliva, tableware, and mother-to-child transmission, resulting in contagion. Therefore, if you have a TB patient in your family, you can get vaccinated against TB. TB vaccination can make family members develop special resistance to TB and reduce the incidence and severity of TB in family members, especially the incidence of granulomatous TB and TB meningitis. After taking the TB vaccine, the body can produce specific immunity against Mycobacterium tuberculosis, preventing the bacteria from reproducing and spreading in the body, and preventing tuberculous meningitis and cornual tuberculosis. To summarize, if there is a tuberculosis patient in the family, it is recommended to receive tuberculosis vaccination, and you can consult the relevant doctors to understand the details.
