The current flu season is displaying unusual behavior, marked by an early start and an atypical geographic progression. With the virus emerging in the West first, health authorities are adjusting their guidance to encourage earlier vaccination.
A key factor in this trend is a new variant of the virus that possesses a mutation designed to bypass existing immunity. Because this variant may be more effective at spreading, getting vaccinated promptly is considered essential to mitigate the impact of the upcoming flu season.
