Each year millions of Americans become sick with the flu, hundreds of thousands are hospitalized and tens of thousands die. Getting the flu shot can reduce the chances of infection. But, at best, the vaccine is only effective 40% to 60% of the time, according to the CDC.

Now Michigan State University researchers have data that show how cellular RNA levels change following infection or vaccination. Their work could help make future flu vaccines work better or even aid in the design of a universal vaccine.
