The Centers for Disease Control and Prevention is launching a $5 million initiative to provide seasonal flu shots this fall to about 200,000 livestock workers in states hardest hit by the bird flu outbreak.
Workers on poultry, dairy and pig farms are at greatest risk of being simultaneously exposed to seasonal flu and the H5N1 bird flu that has infected at least 172 dairy herds in 13 states, according to the Department of Agriculture. Such exposures raise the rare risk of the two viruses exchanging genetic material, a process known as reassortment, to create a new influenza virus that “could pose a significant public health concern by becoming more efficient at spread and potentially more severe,” Nirav Shah, CDC’s principal deputy director, said at a news briefing Tuesday. Widespread seasonal flu vaccination would reduce that risk, he said.
