Surprisingly, flu season can start as early as October and continue as late as May. January and February are generally considered peak flu season—the time when most people get the flu.
The Advisory Committee on Immunization Practices (ACIP) recommended that FluMist Quadrivalent not be used for the 2017-18 influenza season. We encourage patients and caregivers to have conversations with their healthcare providers about this year’s ACIP recommendation as part of discussions around influenza vaccination.
