Most imported beef goes into hot dogs and canned stews, or is brought in as canned corned beef. Last year Argentina got only $15.3 million of this business (one of its biggest customers: Campbell Soup Co. for its beef soups)-and it is working...
Bolivian doctors concluded that the disease was a form of hemorrhagic fever similar to those already known from Manchuria, Korea, India and Argentina. But was the responsible virus the same as any of those from other lands? And what animal or insect transmitted the virus to its human victims?

The doctors found that the killed virus provides 100% immunity if given in three monthly doses. It can also be used to stimulate the formation of protective antibody before a child gets a shot of the more potent live virus. In either case, side effects are slight and infrequent. The investigators gave the live virus vaccine to 296 children who had already had one dose...
