The injection ("flu shot") Vaccine
Flu vaccine is an inactivated vaccine, meaning that it contains killed influenza virus. The killed influenza virus is injected into muscles or skin and stimulates the immune system to produce an immune response (antibodies) to the influenza virus.
What are some preventative measures I can take?
Try to avoid close contact with sick people.
Avoid touching your eyes, nose and mouth. Germs spread this way
Cover your nose and mouth with a tissue when you cough or sneeze.
Clean and disinfect surfaces and objects that may be contaminated with germs like the flu.
While sick, limit contact with others as much as possible to keep from infecting them.
The flu is highly infectious and is a potentially serious viral respiratory infection that can even be life-threatening. Whereas with other viral respiratory infections the symptoms usually are mild and most people can continue working or going to school while ill, with the flu, the symptoms are severe and prolonged and cause individuals to miss days of work or school. The infection stresses the body. In addition, superinfections may occur. Superinfections are bacterial infections that occur on top of a respiratory infection. Bacterial respiratory infections also are a serious type of infection, and the simultaneous viral and bacterial infection can overwhelm the function of the lungs and the body. Among the elderly and the very young, it can cause death. Because of its infectiousness, morbidity (severity of symptoms and time lost from work or school), and the potential for death, it is important to prevent the flu by vaccination. Although there are medications to treat the flu, they are expensive, not as effective as vaccination, and need to be started within 24-48 hours of the start of symptoms.
