Thinking about getting a flu shot or influenza vaccine this year? The influenza vaccine is the best way to prevent the flu, and flu prevention should be a goal for everyone.
According to the CDC, about 5% to 20% of Americans get the flu each year. More than 200,000 people are hospitalized, and about 36,000 people die. These statistics would decrease if more people took advantage of the opportunity to prevent flu with an influenza vaccine or flu shot.
When should I get a flu shot?
Because flu season may begin as early as October and run through May, the best time to get a flu shot is in October or November. You can still get an influenza vaccine in December or later, but earlier may be more beneficial in preventing flu.
What types of flu shots or influenza vaccines are available?
There are two types of flu shots or influenza vaccines available for children and adults.
The first kind is the traditional flu shot. The flu shot does not contain a live virus and cannot cause the flu. This influenza vaccine is an inactivated virus that is given with a needle.
The other kind is a nasal influenza vaccine called FluMist. This influenza vaccine contains weakened viruses, which usually do not cause illness but sometimes can cause flu. The nasal influenza vaccine is recommended only for non pregnant, healthy people, ages 2 years to 49 years.

How does the flu shot or influenza vaccine work to prevent flu?
Both the flu shot and FluMist -- the influenza vaccines -- work by causing antibodies to develop in your body. These antibodies provide protection against infection from the flu virus. This antibody reaction may cause fatigue and muscle aches in some people.
Each year, the flu vaccine contains several different kinds of the virus. The strains chosen are the ones that researchers say are most likely to show up that year. If the choice is right, the vaccine is 70% to 90% effective in preventing the flu in healthy people under 65 years of age.
Who should get the flu shot?
An annual flu shot is recommended for anyone who wants to reduce his or her chances of getting the flu. The flu shot is highly recommended for certain high-risk individuals who are more prone to flu complications, such as pneumonia. The CDC defines higher-risk people as the following:
