Have you gotten your flu vaccine yet this season?
The New York State Department of Health has declared influenza prevalent statewide for the 2026-2027 flu season, with 6,499 cases and 432 hospitalizations reported so far. Tompkins County Whole Health has urged residents to get flu vaccinations now, and flu is typically expected to rise rapidly in December and January.
Why it matters
Flu cases are already widespread in New York State, which is unusual this early in the season, and the declaration arrives well ahead of the December-to-January period when influenza typically accelerates. Earlier vaccination gives protection time to take effect before the expected surge.
The figures come from New York State flu surveillance for the 2026-2027 season, which reported 6,499 cases and 432 hospitalizations so far, compared with a prior season in which flu was not declared prevalent until December 2025. It remains unclear how severe the full season will become or how high the peak will climb.
The players
New York State Department of Health
The state agency responsible for public health surveillance and guidance, including flu monitoring and vaccination recommendations for New York residents.
Tompkins County Whole Health
A local public health provider in Tompkins County that runs immunization clinics offering low or no-cost flu and COVID vaccines.
The details
Flu spreads mainly through tiny droplets released when an infected person coughs, sneezes, or talks. A flu vaccine takes about two weeks after vaccination to build protection, which is why getting vaccinated before cases climb is the standard recommendation. The annual vaccine is recommended for people starting at six months of age.
Timeline
December 2025: Flu was declared prevalent in New York State during the prior season.
December and January: Influenza typically increases rapidly in these months.
Every Friday: Tompkins County Whole Health offers low or no-cost flu and COVID vaccine clinics by appointment, open 9am-12pm and 1pm-4pm.
Health Landscape
The 2024-2025 U.S. flu season, which caused an estimated 51 million illnesses and 45,000 deaths, sets a recent baseline for judging how serious this season may become. New York's early statewide declaration this year contrasts with the prior season, when the state did not declare flu prevalent until December 2025.
If you have not yet had a flu vaccine this season, it is worth scheduling one now, since protection takes about two weeks to develop before flu cases typically surge in December and January. Adults 65 and older and anyone with a health condition should discuss with their doctor whether a high-dose or other specific vaccine is appropriate for them.
The takeaway
Flu is already prevalent in New York State earlier than usual, so vaccination now gives protection time to take effect before the winter surge. Tompkins County Whole Health offers low or no-cost immunization clinics every Friday, by appointment.
What happens next
Influenza typically increases rapidly beginning in December and continuing into January, so the period ahead is the window in which case counts are expected to climb.
