Tuberculosis and Vaccination

Tuberculosis (TB), caused by the bacteria ‘Mycobacterium tuberculosis’ claims approximately 2 million lives a year. The figure would rise to 3 million if the list includes HIV positive individuals who die with active TB. Worldwide, the case fatality rate associated with the disease is nearly 23%. In places where there is a high prevalence of HIV (Africa), the rate is as high as 50 %. The BCG vaccine is recommended in the prevention of primary tuberculosis, especially to prevent the most serious manifestations of the disease. The immunization programme has been estimated to prevent only 5% of all potentially vaccine preventable deaths due to TB. A joint public-private effort must be created to increase public awareness regarding tuberculosis prevention.
