GOOD: Oral Vaccine for Cholera Found Effective in Africa. “Shanchol, which costs less than $2, comes in a vial smaller than an energy shot. It was developed with support from the Bill and Melinda Gates Foundation, and its maker, Shantha Biotechnics, has said that large orders could push the price below $1 a dose. It took until 2010 for the W.H.O. to accept the idea of fighting cholera with vaccines, ‘but now that seems mostly from the school of the overwhelmingly obvious,’ said Rebecca F. Grais, Epicentre’s epidemiology director and an author of the study.”
