Marie-Antoinette’s household follows the court smallpox-inoculation practice for the royal children in the mid-1780s file
Variolation debates after the king’s 1774 inoculation; court physicians mediated risk. Elite adoption of inoculation is a limited infectious-disease control path inside the royal household. In the causal graph this event weakens Infectious-Disease Transmission, a driver that weakens Life expectancy at birth — an improving welfare path.

What the sources establish
Britannica’s wider Bourbon inoculation narrative and Versailles household medical practice place the royal children’s protective inoculation in the mid-1780s court public health file after Louis XVI’s own 1774 inoculation precedent.
Britannica’s Marie-Antoinette/Louis XVI medical-court context and Versailles household narratives independently treat royal inoculation as established court practice.
Established: mid-1780s royal-child inoculation practice in the received medical-court file.
Marie-Antoinette did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. Year-level date.
