Well, this writing full of history and knowledge, but the concern of matter, there are a lot of diseases that have no proper cure in the late history, but now there are proper ways to curb and control the diseases.
but now there are new diseases emerged, due to uncontrolled pollution, and how can we control them, it not restraint through vaccination, its about us, our everyday role to minimize the pollution, if not then this world must be at the verge of disintegration.
your contribution contains worth and awareness about smallpox, the political agenda of that time of pharmaceutical industry, but its the disease which is now under controlled, but the diseases which is now emerged are directly linked with the character of human beings, which does not take on serious manner....
Thanks a lot...
Blessed You...
