This Jan. 2018 photo provided by Jennifer Burrough shows Shawn Burrough in the hospital in San Diego. Jennifer Burrough and her family didn't get flu shots this year after hearing reports that suggested it might not work very well this season. But her 48-year-old Navy veteran husband, Shawn, landed in the hospital and he had trouble breathing and his kidneys started shutting down. He was medically sedated and put on a breathing machine.
