Apparently, many researchers are speculating that that kavaccine we get as babies might be making it easier to fight corona or prevent its rapid spread in the developing world/countries that still administer it. Trials underway, including Western countries now vaccinating healthcare workers. If true, it's good news both for Africans and the rest of the world. Crossing fingers.
https://www.nytimes.com/2020/04/03/health/coronavirus-bcg-vaccine.htmlThe working idea is that it trains the body to fight off a whole host of invaders, including many viruses and bacteria: A kind of 'general' immune response as opposed to a targetted one, training the body to fight a specific virus. Hope it's true. TB immune response isn't uniform even for TB itself, so if it's helping against Corona, there'd still be a difference from individual to individual in how well-protected they'd be. The range for TB vulnerability after vaccine is between 0-80%
