## Fall brings flu prep
As routines return after summer, doctors say the annual flu vaccine belongs on the fall checklist.
## Last season hit hard
The 2025 to 2026 season brought at least 32 million US flu cases, with about 390,000 hospitalizations and 24,000 deaths.

> at least 32 million flu cases
## A new strain surged
A highly mutated H3N2 subclade K strain helped drive a rapid spike, leaving many immune systems poorly prepared.

> highly mutated variant
## Flu is common
Influenza infects roughly 8 percent of Americans each year and spreads easily through respiratory droplets.
## Symptoms can escalate
Body aches, fever, cough and headache are typical. Some infections lead to pneumonia or severe brain dysfunction.

> pneumonia and influenza-associated encephalopathy
## Season starts in October
Flu activity usually begins in October, peaks from December through February, then fades by spring.

> peaking in December through February
## September is still quiet
As of September 5, US flu activity was minimal, which is why doctors say most people do not need the shot immediately.

> minimal activity level
## Protection has a clock
A flu shot protects for about six to eight months. Getting it too early can mean weaker coverage before the season ends.

> six to eight months
## Skip August timing
Pharmacies may stock and promote flu vaccines in August or September, but doctors say those months are early for most adults.
## October is the target
Experts point to October as the best month, and the CDC recommends vaccination by Halloween for the 2026 to 2027 season.

> vaccination by Halloween
## Why October works
By October, flu activity is more likely to be starting, and the vaccine should carry further into winter.

> The vaccine will last further into the season
## Some kids need two
Children under 8 who have never had a flu shot need two doses spaced apart, so they may need to start earlier.
## High risk may go early
People with higher risk of complications, including those with asthma, may also consider earlier vaccination.
## Shots cover A and B
Seasonal vaccines are updated each year and target influenza A and B, the strains linked to most serious seasonal illness.

> updated every year
## Immunity takes time
The body can take up to two weeks to build antibodies after vaccination, so plan ahead before crowded indoor events.

> up to two weeks
## Risk is not equal
Older adults, people with chronic conditions, pregnant women and children under 5 face higher odds of serious flu complications.
## Super flu worried doctors
Last season’s strain caused familiar symptoms, but doctors warned illness could be more severe, especially in children.

> more severe illness, especially in children
## Prevention still matters
Health officials advise handwashing, avoiding sick contacts and treating flu with rest, fluids, symptom relief or antivirals when needed.
## Key takeaway

For most people, October is the sweet spot for a flu shot, early enough to build immunity and late enough to last through winter.
