12 more kids have died, bringing the 2025-26 pediatric death toll to 44 so far. This time last year the total was 27 — & last year went on to be a record year for kids dying from flu. These deaths are reported on a lag; more will come, sadly.
CDC says ~90% weren't vaxed.

This is up 245 cases in a week.
