Bacillus Calmette-Guerin vaccine can modify both innate and adaptive immunity and, thereby, provide immunity not only against Mycobacterium tuberculosis but also other pathogens.
BCG vaccine provides an artificial and active immunity. Justify
BCG vaccine provides an artificial and active immunity by stimulating the immune system to recognize and fight against the bacteria that cause tuberculosis. This is achieved through the introduction of weakened Mycobacterium bovis, which triggers a response from the body's immune cells, leading to the production of antibodies and memory cells that can provide long-term protection against future infections. Additionally, the BCG vaccine also helps in reducing the severity of tuberculosis symptoms and preventing the spread of the disease to others. It is particularly effective in protecting against severe forms of tuberculosis, such as meningitis and disseminated disease, in young children. Additionally, BCG vaccination has been shown to reduce the severity of tuberculosis symptoms in those who do contract the disease, further highlighting its effectiveness in providing active protection. Moreover, studies have suggested that the BCG vaccine may also provide some level of protection against other respiratory infections, such as pneumonia and upper respiratory tract infections. This suggests that the benefits of BCG vaccination extend beyond tuberculosis alone, making it a valuable tool in improving overall respiratory health.
