Flu shots are available in different areas of the country at different times of the year. Flu.gov offers people a vaccine finder on its website that can help find the closest vaccines.
According to Flu.gov, the typical flu season begins in the fall and lasts through February. In some areas, the first cases of flu are reported as early as October and last through May. Flu vaccines are usually distributed before the first cases are reported.
The flu is most dangerous for seniors, children and people with chronic health conditions. These people should receive a flu vaccine as soon as they become available.
