aThe flu vaccination is offered to everyone with an increased risk of catching the virus or having complications from it. This includes everyone over the age of 65, even if they are fit and well! Children from the age of two years old to year five in school (age nine or 10) are also offered a vaccine, as well as pregnant women and all children and adults with a longterm medical condition, such as asthma or diabetes. The constituents of the flu jab change each year to try to best fight the changing flu viruses and as such you need a new vaccine every year to make sure you’re protected and keep you in your fit and healthy state.
