Why do some people end up in bed feverish, hacking and sneezing for days from the flu — when others seem to never get sick?
To answer that question, University of Michigan researchers did the first study of its kind: They infected 17 healthy people with the flu virus and discovered that everyone who is exposed to the flu actually is affected by it, but their bodies just have a different way of reacting to it. Half of the study participants got sick; the other half didn’t notice a thing.
“Many people might conclude that if you are exposed to a virus and you don’t get sick, it’s because the virus didn’t stick or it was so weak, it just passed right through your system and your system didn’t notice. That’s not a correct notion,” says Alfred Hero, professor at the University of Michigan College of Engineering and author of the study, which was published Thursday in the journal PLoS Genetics.
He continues, “There is an active immune response which accounts for the resistance of certain people getting sick, and that response is just as active as the response we all know and hate, which is being sick with the sniffles, fever, coughing and sneezing. It’s just that the responses are different.”

I usually get one cold a year, and a bad stomach bug once every 3 to 5 years. My husband, on the other hand, gets whatever is coming through - every time.
It looks like this study gives us a glimmer of insight into the differences between people and their immune responses.
