 * 1) Why is the flu a serious disease?
 * 2) The flu is a serious disease because it can lead to hospitalization, or even death if not treated. Because the flu is a virus, it infects every cell in the body, making it hard for the white blood cells to get rid of it faster. The flu is also serious because it's not the same every year. The flu changes, which makes it harder because they need to make a different vaccine every year.
 * 3) How is the flu spread?
 * 4) The flu is spread through multiple ways. If someone coughs or sneezes, and someone else breathes in their "vapors", that person can become infected. Also, if an infected person has coughed into their hands then touched a door knob or something of the sort, and then an uninfected person comes along, uses that same doorknob, the touches their mouth, nose or eyes, they can become infected.
 * 5) What are the benefits and risks of a flu vaccine?
 * 6) Some benefits of the flu vaccine are that it's easier to avoid the flu, and it will save you from the sickness. However, if you are allergic to eggs, then you can't take the vaccine because it is made in eggs. Also, the vaccine may not work because of the virus placebos that are in the vaccine.
