Because influenza viruses are constantly changing, the Centers for Disease Control and Prevention (CDC) recommends an annual flu vaccination for protection against the flu. The flu vaccine is commonly available as early as September, and throughout the flu season, which generally ends in early May. It usually takes about two weeks for the vaccine to work, and its protection will last throughout the flu season.
This vaccine is given as an injection into the arm or thigh muscle, which is known as an intramuscular (IM) injection. The vaccine contains an inactive, or killed, virus so it is not possible for someone to get the flu from the vaccine.
There is also a nasal spray version of the flu vaccine available.
In this video, watch Rajesh Govindaiah, MD, Memorial Health System’s Chief Medical Officer, provide more information about the flu and its symptoms and the benefits of getting a flu shot.
