The first type of influenza virus you're exposed to may set your lifetime ability to fight the flu.
Researchers with McMaster University and University of Montreal found that being born in an H1N1 year or an H3N2 year matters. Following a phenomenon known as antigenic imprinting, the study revealed that early exposure to one of these two flu strains permanently affects your immunity.<...
Fighting the flu can be an unpleasant experience -- but the misery may not stop there.

Pregnant women can take comfort in new findings that suggest flu vaccines won't harm their fetuses.

Good news for kids: Next flu season, you can avoid a painful needle jab and get the nasal vaccine spray instead, according to a leading U.S. pediatricians' group.
In recent flu seasons, the American Academy of Pediatrics recommended the shot over the nasal spray -- except if a child refused a shot -- due to questions about the nasal spray's effectiveness. However, changes to the nasal...
