Great to see most of the HN comments here wasting their time freaking out about too many brown babies living in the world. (Filter it through whatever level of indirection you like, that's fundamentally the core of these freakouts.) Anyway, it'll be interesting to see if these results hold up, because these are very outsized effects at very low cost compared to many other disease interventions. Also, it'll be interesting to see how much this is due to body weight versus other effects. Antibiotics are routinely used in livestock for weight gain not for disease control, it may be that weight gain gives a significant survival advantage for other conditions, such as enteric diseases, independent of their antibacterial effects. In any event, this has the promise to become an important tool in reduction of child mortality in developing countries and that will have a tremendous number of positive follow-on results (in addition to the lives saved, of course).
