Flu vaccinations begin in early September and continue through the winter. While influenza outbreaks can occur as early as October, most of the time influenza activity peaks in January or later.
There are two ways to get vaccinated: 1. The “flu shot” – a vaccine (containing killed virus) injection. The flu shot is approved for use in those older than 6 months, including both those in good health and those with chronic medical conditions. 2. The nasal-spray flu vaccine – a vaccine made with live, weakened flu viruses that do not cause the flu. It is approved for use in healthy people age 2 to 49 who are not pregnant.
