The best way in which you can save your children from flu is by getting them vaccinated once a year. It is also the first thing that you should do, especially when your child is younger than 5 years. This is, in any case, is the most vulnerable age group in the context of this particular disease. With a flu vaccine, you would be able to reduce risks such as flu illness, hospitalization, and death. If your child is 6 months at least you should get her or him vaccinated each year. Babies younger than that are at higher risk but they are not supposed to be given such vaccination.
