The best way to protect yourself and your loved ones against influenza (flu) is to get a flu vaccine every flu season. Flu is a contagious respiratory disease that can lead to serious illness, hospitalization, or even death. CDC recommends everyone six months and older get an annual flu vaccine.

Flu vaccines have a good safety record. Hundreds of millions of Americans have safely received flu vaccines over the past 50 years. Extensive research supports the safety of seasonal flu vaccines. Each year, CDC works with the U.S. Food and Drug Administration (FDA) and other partners to ensure the highest safety standards for flu vaccines.

You should get a flu vaccine by the end of October. However, as long as flu viruses are circulating, vaccination should continue throughout flu season, even in January or later.
