One thing that China is doing right is exploring the use of low cost, high strength Vitamin C. I having been using Vitamin C 3 or 4 times a day, from 3 to 6 grams a day for more than 45 years. At 81 years I am in good health and almost never sick. As reported in the link below, 3 Chinese trials are using Vitamin C in amounts as high as 24 grams, and possibly intravenously. If this proves successful, Big Pharma will not be happy, Vitamin C is inexpensive.
