Anyone can get the flu, no matter how healthy they are. The Center for Disease Control and Prevention (CDC) recommends all people (with some exceptions) ages 6 months and older get a flu shot to protect themselves and others from the flu.
When is Flu Season?
Flu season typically strikes the U.S. beginning in October and lasts through May, with infections usually peaking from December through February. The Centers for Disease Control and Prevention (CDC) estimates that the flu has resulted in between 9 and 41 million illnesses, 140,000-710,000 hospitalizations and 12,000-52,000 deaths annually between 2010 and 2020.
How Bad Will This Flu Season Be?
No one knows for sure how to accurately predict how dangerous the newest flu season will be. And that goes for this year’s 2024-2025 flu season. However, the recommended 2024-25 US flu vaccines are three-component (trivalent) vaccines instead of four-component (quadrivalent) compared to on prior years because the influenza B/Yamagata viruses are no longer actively circulating.

“Increased flu vaccination for both adults and children could help reduce the risk of a more severe flu season,” said Dr. Armando Paez, chief, Infectious Disease Division, Baystate Health.
Which Flu is Worse – A or B?
You may have heard that there are generally two types of flu virus each year – flu A and flu B. Is there one that’s worse to get than the other? According to Dr. Amy Starmer, Pediatrician at Baystate General Pediatrics, “Both influenza A and B can cause illness, and the severity can vary each season. The impact may differ among individuals, and susceptibility can change. It’s essential to follow the advice of your doctor or pediatrician, who can provide specific guidance based on the current flu season and you and your child’s health.”
When to Get the Flu Shot
The 2024-2025 flu vaccines are now available. Ideally, the CDC recommends that everyone should be vaccinated by the end of October since the flu can begin in earnest at any time and it can take up to two weeks for the vaccine to build up antibodies to protect you from the flu. Ideally, you want to have maximum immunologic protection before the peak of the flu season but timing this is not easy.
“But it is never too late to get the flu shot to protect yourself throughout the long flu season,” said Dr. Paez. The best time to get a flu shot is as soon as possible, regardless of how late in the season it is.
Dr. Starmer adds, “While it’s commonly recommended to get the flu shot in the early fall, getting vaccinated later in the season is still beneficial. The flu season can extend into spring, so even getting vaccinated in January or later can provide protection. It’s better to get vaccinated late than not at all.”
