Bird Flu Vaccine Works In Chickens

Scientists are testing a vaccine strain that may protect turkeys and is 100 percent effective in protecting chickens from bird flu. The USDA is seeking federal funding to stockpile the vaccine nationally. The vaccine targets the H5N2 virus that killed 48 million birds in 15 states this spring. Development is part of the USDA's preparation for a possible outbreak recurrence. Scientists believe the virus was spread by droppings of wild birds migrating north this spring. They're concerned it could return this fall when birds fly south for the winter or again next spring.
