The flu vaccine helps protect children who receive it, as well as their younger siblings
Children under two years are significantly more at risk of serious illness from influenza if they have older brothers or sisters, new research has shown. The flu virus spreads through the air when people cough and sneeze without covering their nose and mouth. With children of all ages mixing at parent and toddler groups, in day nurseries and at childminders, and because young children don’t always cover their noses or mouths when coughing or sneezing the virus can spread very quickly among them.
