BCG (Tuberculosis) vaccination. Injection needle is inserted intradermally under the skin during a BCG (Bacillus Calmette-Guerin) vaccination. The needle must be inserted very superficially in this way,in order to raise a blister. The vaccine injected is a live attenuated strain of bovine Mycobacterium bovis,which stimulates sensitivity to M.tuberculosis,the bacteria which causes tuberculosis in humans. The blister progresses to a papule or a benign ulcer within 6-12 weeks,and a scar remains. Normally the upper arm or thigh is injected. Pulmonary tuberculosis affects the lungs and,apart from vaccination prevention,may be cured with antibiotic drugs | |
