Things to know about the flu shot:

• It takes about two weeks for the flu vaccine to take hold and be protective.
• Getting a flu shot cannot give you the flu. Some people can get mild symptoms in the first few days as their body develops antibodies.
• The flu vaccine comes in several varieties. Consult your doctor to determine which is best for you.
