Summary
- The 2025-26 flu season has been one of the harshest in memory, with the CDC estimating at least 15 million illnesses, 180,000 hospitalizations and thousands of deaths — including dozens of children — by early January 2026.
- Flu surged in 45 states, pushing doctor-visit levels to their highest in nearly 30 years.
- A mutated 'subclade K' strain partly evades the vaccine; it followed 2024-25, the deadliest pediatric flu season since the CDC began tracking, with 289 child deaths.
The question
Vaccine mismatch is making seasonal flu far more dangerous.
