Vietnam is preparing to test a rather old (~100 years) vaccine called BCG, previously used to prevent turberculosis, to see if it works against the CCP virus.
In principle I'm against vaccines but this one might be so old that it isn't nearly as dangerous as the Big Pharma crap they are injecting today.
Somehow, injecting people with supposedly-dead TB just doesn't seem like a good idea, esp for a virus with a low mortality rate like CCP virus.
