As I said before, diddling around with vaccines is like diddling around with antibiotics. We all need to wear bonoglasses all the time.
Those are tight-fitting wrap-around glasses. You can forget the mask.
We can now expect variations to dance around the vaccines. The poor of the world won't even get a vaccine before it is useless. Then we'll suck up all the new vaccines, and start the circle again.
And I pity the few forests in India. Where do they get all the firewood?
