WASHINGTON ( AP ) _ The world's first vaccine against the leading cause of childhood diarrhea _ a virus that hospitalizes 55, 000 American children each year and kills 1 million in other countries _ has won approval by the U . S . government.

The current vaccine, which has been licensed for less than a year, has a success rate of 50 percent to 70 percent against the rotavirus disease, a potentially deadly intestinal infection that hospitalizes 4 percent of all children under 5 and kills 2, 000 infants a day worldwide, mostly in developing nations.

Some drug companies and academic researchers are working to reduce the lead time and prepare more effective vaccines by incubating the virus in monkey cells rather than eggs _ and by using genetic engineering to remove much of the guesswork of preventing a disease that kills an average of 36, 000 Americans and hospitalizes another 114, 000 a year.

Drug companies and academic researchers say they could reduce the lead time and prepare more effective vaccines by incubating the virus in human and monkey cells rather than eggs _ and by using reverse genetics to remove much of the guesswork of preventing a disease that kills an average of 36, 000 Americans and hospitalizes another 114, 000 a year.
