Do you plan to get your annual flu and COVID-19 vaccinations this season?

The Centers for Disease Control and Prevention classified the 2025 influenza season as one of the most severe in recent years. This retrospective look examines health outcomes in Oklahoma, where officials are now projecting a potentially milder season for 2026.

Why it matters

Understanding past influenza severity helps medical professionals calibrate annual vaccination strategies, as the virus is continuously mutating. Proper vaccination remains a primary tool to mitigate the risk of severe or fatal outcomes from circulating flu strains.

In Oklahoma, annual influenza hospitalizations typically range from 2,000 to 4,000, with 50 to 250 adult deaths recorded annually. Flu vaccines generally offer an effectiveness range of 40% to 60%.

The players

Centers for Disease Control and Prevention

This federal agency is responsible for protecting public health through the control and prevention of disease.

The details

Health groups update vaccines each year to match evolving strains, while patients are encouraged to receive annual COVID-19 shots. A new mRNA flu vaccine for adults aged 50 and older is expected soon, though it may have a two-fold higher incidence of side effects than current options.

The severe influenza season occurred throughout 2025.
Experts anticipate a milder influenza season in 2026.
Health officials recommend flu and COVID-19 vaccinations between Halloween and Thanksgiving.

The Big Picture

This assessment follows the protocols set by the Centers for Disease Control and Prevention for tracking and classifying seasonal viral severity.

Residents should plan to receive their annual flu and COVID-19 vaccines between Halloween and Thanksgiving to maximize protection against circulating strains. Patients over 50 should consult their providers regarding the anticipated availability and potential side effects of the new mRNA flu vaccine.

The takeaway

Annual vaccination is the most effective way to transform potentially fatal influenza cases into manageable, mild ones. Staying informed about vaccine updates and recommended administration windows is essential for maintaining community health through the winter months.
