Flu vaccination is available every year to certain groups to help protect adults and children at risk from flu
and its complications. Flu can be unpleasant, but if you’re otherwise healthy, it’ll usually clear up on its own
in about a week. However, in those aged 65 and over; pregnant women; children and adults with an
underlying health condition (such as long-term heart or respiratory disease); and children and adults with
weakened immune systems flu is more likely to cause serious complications.
