In the United States, over 200,000 people spend time in the hospital with flu complications each year, and about 36,000 people are estimated to die as a result of flu. It is estimated that, globally, 250,000-500,000 people die each year as a result of flu. In industrialized countries, the majority of deaths occur among people over the age of 65. A flu epidemic—where a large number of people in one country are infected—can last several weeks. Health experts and government agencies throughout the world say that the single best way to protect oneself from catching flu is to have a flu vaccination every year.

Protection begins about 2 weeks after receiving the vaccination. Seasonal flu vaccinations should start in September or as soon as the vaccine is on hand, and continue throughout the flu season, into January, and beyond.This is because the timing and duration of influenza seasons are never the same.
