    Health

    BCG vaccine

    Syllabus: GS 2/Health

    In News

    • Recently , The centenary celebration of the discovery of the Bacillus Calmette-Guérin (BCG) vaccine was observed.
      • It was first used in humans in 1921.

    About 

    • The Bacillus Calmette-Guérin (BCG) vaccine is a live attenuated strain derived from an isolate of Mycobacterium Bovis.
      • A live attenuated vaccine means that it uses a pathogen whose potency as a disease producer has been artificially disabled, but whose essential identifying characteristics which help the body to increase an immune response to it have been left unchanged.
    •  It has been used widely across the world as a vaccine for Tuberculosis.
    • It was developed by two Frenchmen, Albert Calmette and Camille Guerin. 
    • Currently, BCG is the only licensed vaccine available for the prevention of TB.
      •  It is the world’s most widely used vaccine with about 120 million doses every year and has an excellent safety record. 
    • In India, BCG was first introduced on a limited scale in 1948 and became a part of the National TB Control Programme in 1962.
    • Efficacy: 
      • It has high efficacy in the UK, Norway, Sweden and Denmark; and little or no efficacy in countries on or near the equator like India, Kenya and Malawi, where the burden of TB is higher. 
      • These regions also have a higher prevalence of environmental mycobacteria. It is believed that these may interfere with the protective effect against TB. 
      • However, in children, BCG provides strong protection against severe forms of TB. 
      • Interestingly, it has been observed that in some countries that have had BCG vaccination as a national policy, the burden of SARS CoV-2 morbidity and mortality was significantly less compared to countries that did not. 
        • Clinical trials to know if this is indeed true, are underway, including in India.

    About Tuberculosis

    • It is caused by Mycobacterium tuberculosis (bacteria) and it most often affects the lungs.
    • TB is spread through the air when people with lung TB cough, sneeze or spit. A person needs to inhale only a few germs to become infected.
    • Directly observed treatment (DOTs): Short-course (DOTS, also known as TB-DOTS) is the name given to tuberculosis (TB) control strategy recommended by the World Health Organization.
    • It was also deployed by India to curb the menace of TB.

    Pashmina Shawls

    Syllabus: GS3/ Indian Economy & related issues

    In News

    • A Centre For Excellence (CFE) has been set up in J&K to restore the lost hand-driven processes involved in the intricate shawl weaving industry.

    About

    • Over the years, women employment in this sector has reduced due to poor wages, old techniques of weaving and the emergence of machines.
    • Spinning on a traditional Kashmiri charkha allows longer threads of Pashmina wool with fine hair-like size, unlike machines, and adds to the softness and warmth of the product.
    • In the backdrop of this trend, the Directorate of Handicrafts and Handloom, Kashmir, has announced a Minimum Support Price (MSP) for geographical indication (GI)-certified hand-made Pashmina shawls “to sustain the old techniques”.

    Pashmina Shawl

    • They are a fine variant of shawls spun from cashmere wools. Cashmere wool itself is obtained from the Changthangi goat (Capra aegagrus hircus) native to the high plateau of Ladakh.
    • Goats used for pashmina shed their winter coat every spring. One goat sheds approximately 80–170 grams of the fibre. In the spring (the moulting season), the goats naturally shed their undercoat, which regrows in winter. This undercoat is collected by combing the goat, not by shearing, as in other fine wool. 
    • The shawl made up of pashmina wool was promoted as an alternative to Shahtoosh shawl. The reason being that Shahtoosh Shawls are made from the Tibetan Antelope.
