Flu Season Information and Resources


2023 National Influenza Vaccination Week

National Influenza Vaccination Week (NIVW) is an awareness campaign promoted by the Centers for Disease Control and Prevention (CDC).

The annual observance in December reminds everyone six months and older that there is still time to protect yourself against severe illness this flu season.

This year, the CDC is using the phrase "wild to mild" to promote the benefits of the flu vaccine, specifically how the vaccine can significantly reduce the chances of severe illness in people who get sick with the flu.
