Darwin's public file includes dated support for vaccination as an infectious-disease heading, not as a unique trial he ran
Darwin's public file includes dated support for vaccination as then practised. Charles Darwin's documented role is: Correspondence and later public remarks place him with vaccination against smallpox as then practised. In the causal graph this event weakens Infectious-Disease Transmission, a driver that weakens Life expectancy at birth — an improving welfare path.

Read the full account
Darwin's public file includes dated support for vaccination as then practised. Charles Darwin's documented role is: Correspondence and later public remarks place him with vaccination against smallpox as then practised. Jenner is the named prior. He did not run a national campaign.
Context
Jenner is the named prior. Sharing physicians in the correspondence is required. Driver infectious-disease-transmission is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
That reading is an impact-path choice, not a property stored on the Fact itself.
Why it matters
The welfare reading on this path is improving.
Naming Charles Darwin does not delete co-authors, institutions, or later transmitters. The lag from 1871-01-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
