This year's flu season is not expected to be severe by medical professionals. However, concerns are rising due to a steady decline in flu vaccination rates, dropping from 52% in 2021 to less than 44% during the 2025-2026 flu season, according to CDC data. This trend, exacerbated by increased vaccine hesitancy post-COVID-19, could lead to a greater number of infections and widespread impact, even if the virus itself is not particularly aggressive.
The decline in vaccinations could place significant pressure on healthcare infrastructure. The 2024-2025 flu season, for instance, saw an estimated 37 million flu-related medical visits and 1.3 million hospitalizations, a substantial increase compared to 18 million visits and 470,000 hospitalizations in the 2023-2024 season. Dr. Gabriela M. Andujar Vazquez, a hospital epidemiologist, warns that strained hospitals, emergency rooms, and clinics could lead to delays in patient care and potential bed shortages.
Medical groups, including the American Medical Association, are urging individuals aged 6 months and older to get vaccinated. The flu shot, while not preventing all infections, significantly reduces the severity and duration of illness, and decreases hospitalizations in older adults by 31%, as per the Vaccine Integrity Project. It takes about one to two weeks for the body to develop an immune response, with peak antibody levels occurring three to four weeks post-vaccination, offering protection for four to six months.
While the CDC typically runs a fall campaign for seasonal immunizations, the agency has been notably quiet this year under the second Trump administration, updating its guidance to simply follow last year's recommendations. This lack of a proactive federal push has prompted leading U.S. medical groups to collaboratively issue guidelines and emphasize the scientific backing of vaccines to counteract potential public confusion.
Beyond vaccination, experts recommend preventive measures such as handwashing, improving ventilation, wearing masks in crowded indoor areas, and staying home when symptomatic. For those who do contract the flu, mild cases can be managed with rest and fluids. High-risk individuals, including the elderly and those with chronic conditions, should consult a physician about antiviral medications like Tamiflu, which are most effective if started within two days of symptom onset.
