What Is the Flu?
Influenza, otherwise known as the flu, is an illness caused by a virus. It can cause symptoms such as a sore throat, runny nose, fever, sneezing, coughing, headaches, and weakness. The flu can be contagious, meaning it can pass from one person to another. Someone with the flu should stay home from school or work to avoid passing it on.
Why Get a Flu Shot?
It’s in your best interest to get a flu shot this year. Studies have shown that this vaccine can protect you from getting sick.
It is especially important for vulnerable populations, such as the young, pregnant women, and seniors, to get a flu shot. This can prevent complications from the flu.
How Is the Flu Shot Delivered?
The flu shot can be delivered by injection or through a nasal spray. The vaccination contains a low dose of the dead flu virus, which help the body produce antibodies that help fight the virus if it arises. Flu shots should be administered at the beginning of “Flu Season.” This starts approximately in October, although flu shots are available through at least January.
