Flu is about, if you haven’t yet had your annual flu shot it’s not too late to protect yourself. Because the flu virus is constantly changing, you need to get vaccinated every year.
Every year, the flu vaccine changes too, so it protects against the strains of flu virus which are most likely to be around during this winter. Even if you received a flu shot towards the end of the last flu season, you should still be vaccinated again before this flu season.
