Research Shows How Some Folks Resist Getting Sick With the Flu, University of Michigan Study
Your immune system response to a flu virus determines whether or not you will get sick, and that immune reaction can be observed through gene activity, according to a new study. Researchers examined more than 22,000 genes in 267 blood samples from 17 healthy volunteers who were infected with a flu virus. There were significant and complex differences in the immune responses between the half of the participants who got sick and those who didn't, the investigators found.
