BCG is bacillus Calmette-Guérin (BCG) is a live attenuated strain of Mycobacterium bovis
It is used in the prevention of Tuberculosis but it does boost the immune system.
Thanks for the clarification. I had interpreted the “or” to mean BCG was HCQ. I wondered why they referred to it as a “vaccine”.
Universal administration of HCQ especially if the Indians are getting enough zinc in their diet would explain the fewer cases.
Not sure about the effects of BCG.
