Some genuinely good news to close this month's newsletter: the US death rate fell to its lowest level ever recorded in 2025 -- 689.2 deaths per 100,000 people, a 4.6% drop from 2024. The decline showed up across every age group and both sexes, and life expectancy is expected to hit a new record once the final numbers are calculated. A big driver: drug overdose deaths kept falling, especially among adults 25 to 34, where the death rate dropped from 124.5 to 111.1 per 100,000 in a single year -- a real bend in a decade-long, opioid-driven trend.
But one line in the data stands out against all that good news: influenza climbed from the 11th to the 8th leading cause of death nationally this year, at the same time adult flu vaccination coverage fell to its lowest point in about seven seasons -- 41.9%, down from 52.2% just four seasons ago. Almost every other mortality trend improved in 2025. The one respiratory illness with a decades-old, well-studied vaccine moved in the wrong direction. If you haven't scheduled your flu shot yet, this is a good nudge to put it on the calendar for October.
