vaccin bcg danger

In a section on the immunology of tuberculosis, Cui posed a series of basic questions and detailed answers about vaccination (Cui 1936, 17–19). To emphasize the reliability of BCG, Wang discussed its acceptance by the international immunological community. Content: Numerous epidemiological, clinical and immunological studies demonstrate that BCG vaccination impacts the immune response to subsequent infections, resulting in reduced morbidity and mortality. He suggested vaccinating all infants at birth, as well as children and adults who had not already contracted the disease, “because the risk of exposure to cases of tuberculosis in China is so ubiquitous” (Qiao 1948, 571–573). However, a full understanding of the molecular mechanisms that underlie this phenomenon is still evolving. Hara Sakae. 2020 Oct 29;16(10):e1008969. “Bacillus Calmette-Guérin (B.C.G.) By the early 1930s, tuberculosis was identified as a crisis of Chinese health, society, and family. Qiao, Shumin [Chiao Shu-min]. Soon, Wayne S. 2016. These persistent qualms about BCG spoke to broader concerns about the use of xizhuang ji to deal with a disease that was historically intractable to biochemical interventions. isoniazid, rifampin, Rifadin, rifabutin, Valstar. Flanagan KL, Best E, Crawford NW, Giles M, Koirala A, Macartney K, Russell F, Teh BW, Wen SC. More serious complications, such as abscesses or bone inflammation, are rare. eCollection 2020 Oct. Sultan Qaboos Univ Med J. In the decades after Robert Koch’s 1890 failed attempt to use this extract of tubercle bacillus as the basis for a tuberculosis vaccine, the activity and toxicity of the bacillus remained poorly understood in Europe. provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. It seems likely that he was drawing on scientific evaluations of BCG in medical journals. A native of Chengdu, Wang had trained at the medical school at Hanoi established by the French colonial government of Indochina, then pursued medical studies in France before taking up a position as chief physician at the Ren’aitang yiyuan (Ren’aitang Hospital) in 1913. "Product Information. “B.C.G. Whereas most accounts of the introduction of BCG to China focus on the rapid expansion of immunization programs under the People’s Republic in the early 1950s, physicians and researchers working for the Nationalist administration actually laid the groundwork for these programs well before 1949. 2011. Tuberculosis (TB) caused by Mycobacterium tuberculosis continues to be a leading cause of mortality among bacterial diseases, and the bacillus Calmette-Guérin (BCG) is the only licensed vaccine for human use against this disease. Aronson, Joseph D. 1948. “Blood, Soy Milk, and Vitality: The Wartime Origins of Blood Banking in China, 1943–45.” Bulletin of the History of Medicine 90 (3): 424–454. Translated by Hong Shilü. In July 1921, the pediatrician Benjamin Weill-Hallé successfully gave an oral vaccine using live, attenuated tubercles to a Parisian infant (Gheorgiu 2011, 50; Liu et al. This attention to means of employing vaccines in China’s distant borderlands likely reflected the experiences of microbiologists in the wartime hinterland, and indicated that microbiologists like Qiao were now thinking about vaccination on a national scale. Serious and fatal disseminated BCG infections have occurred with intravesical administration. To its promoters in the 1930s, BCG vaccination offered China a practical opportunity to prevent tuberculosis on a mass scale, relying on technical, biochemical methods rather than extensive and long-term social transformation. The Shanghai Pasteur Institute continued to distribute BCG vaccines after the city fell to the Japanese in 1937, and vaccinated a total of 5,661 people between 1937 and 1946. The international health organizations that emerged in the wake of that war promoted BCG as a solution to this emergency.
