Vaccination for healthy adults is a personal choice. Influenza is usually a brief illness with a low risk of complications in this group.
However, a lot of people choose to be immunised as influenza is unpleasant and can put you in bed for several days.
Many working people choose vaccination to reduce time off work, especially the self-employed.
Vaccination can prevent disruption to other important activities in the flu season, such as exams, overseas travel or a wedding.
Nursing home staff and other adults caring for the elderly or infirm should be vaccinated every year to protect those in their care.
