(CNN) -- It's National Influenza Vaccination Week and the Centers for Disease Control says getting the vaccine is the best way to prevent the flu.
December through February is the peak flu season in the United States, but the flu can last through May.
The CDC recommends getting a yearly flu vaccine for everyone 6 months of age and older, but does not recommend the nasal spray flu vaccine.
Those at the highest risk of catching the flu and developing serious flu-related complications are pregnant women, children younger than 5 years old- but especially children younger than 2 years old- and people 65 years of age and older.
Be sure you are taking precautions to also avoid the virus, and avoid contact with sick people.
If you do catch the flu, limit your contact with others, cover your nose and mouth when sneezing, and wash your hands often.
Enjoy this holiday season and make sure you're protected this flu season.
