WASHINGTON – A July 2 Cronkite News Service story on a swine virus that has spread to Arizona hog herds incorrectly reported that a vaccine for porcine epidemic diarrhea virus was not available. In fact, the U.S. Department of Agriculture issued a conditional license on June 16 to Harrisvaccines Inc. for its vaccine, the first to win conditional approval for controlling PEDV. The story here has been updated to reflect the correct information.
