Answers
Answer:
The formulation of international requirements for the manufacture and control of BCG vaccine was first considered by the WHO Expert Committee on Biological Standardization in its thirteenth report. In its fourteenth report, the Committee requested WHO to make arrangements as soon as possible for the formulation of such requirements. These requirements were approved by the WHO Expert Committee on Biological Standardization at its eighteenth meeting and appeared as Annex 1 to its report.
Mycobacterium tuberculosis (Mtb), the ethiological agent of tuberculosis (TB), is a leading cause of human disease and death, particularly in developing countries. In the global context, TB in intimately linked to poverty, and control of TB is ultimately a question of justice and human rights. In some areas with a high burden of TB, existing strategies for TB control are currently overwhelmed by the rising numbers of cases of TB occurring in parallel with or the HIV/AIDS pandemic. Emerging mycobacterial drug resistance is further complicating the situation. After decades of steady decline, the incidence of TB is also increasing in industralized countries, mainly as the result of outbreaks in particularly vulnerable groups.
The bacille Calmette-Guérin (BCG) vaccine has existed for 80 years and is one of the most widely used of all current vaccines, reading >80%of neonates and infants in countries where it is part of the national childhood immunization programme. BCG vaccine has a documented protective effect against meningitis and disseminated TB in children. It does not prevent primary infection and, more importantly, does not prevent reactivation of latent pulmonary infection, the principal source of bacillary spread in the community. The impact of BCG vaccination on transmission of Mtb is therefore limited.
Answer:
BCG, or bacille Calmette-Guerin, is a vaccine for tuberculosis (TB) disease. Many foreign-born persons have been BCG-vaccinated. BCG is used in many countries with a high prevalence of TB to prevent childhood tuberculous meningitis and miliary disease.
