# Louise Pelletier dies after delayed rabies treatment in Pasteur’s Paris series

Date: 1886

## The fact

In 1886 Louise (often Jeanne-Antoinette) Pelletier, a child bitten and brought late to Paris, died after [Pasteur](/people/louis-pasteur)’s rabies inoculations, one of the named failures inside a series presented as largely successful. Pasteur’s March 1886 Academy paper had already counted hundreds of treatments; failures were politically costly and sometimes minimised in popular tellings.

## Context

Post-exposure vaccination cannot outrun virus already in the central nervous system. Late presenters died in every early series. The laboratory still accepted desperate families, which is both access and risk. Grancher and colleagues injected. Sharing the clinic does not erase Pasteur’s protocol. Do not invent a malpractice judgment that a French court did not issue.

## Evidence and sources

The Académie des sciences at https://www.academie-sciences.fr/ is the official home of the 1886 case communications. PMC Pasteur historiography at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1200696/ independently insists that the human series included failures and later argument, not only Meister.

## Significance

Health-system path as a documented limit and harm. Medium confidence on the exact civil-registration spelling of the child’s names. Meister’s improving row is not cancelled; it is not copied here.

If a number is not in the two records named above, it is not supplied here.

## What is established and what is not

Established: at least one named child in the 1886 Paris series died after delayed treatment. Not established: a complete list of all treatment deaths, or that the laboratory caused rabies rather than failing to stop it. Contribution is recorded as His laboratory accepted a late case. Physicians injected; the child’s prior delay was parental and provincial. Complex. The impact note is A documented death after post-exposure treatment shows the method’s limit when incubation is advanced, a health-capacity worsening path of medium confidence. The dated heading stays Louise Pelletier dies after delayed rabies treatment in Pasteur’s Paris series on 1886-12-01, not a later statue, UNESCO listing, or school film. Printers, unnamed clerks, and later editors may appear in the same file without becoming this instrument.

Confidence is stated on the impact path, not hidden in adjectives. A delayed-case death is not Meister’s survival. Mixed effects of Louise Pelletier dies after delayed rabies treatment in Pasteur’s Paris series are separate paths.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

The attached driver is health-system-capacity. The welfare reading used in this dossier is worsening. That reading is an impact-path choice, not a property stored on the Fact itself.

Shared responsibility is part of Louise Pelletier dies after delayed rabies treatment in Pasteur’s Paris series. Naming Louis Pasteur does not delete co-authors, institutions, or later transmitters. The lag from 1886-12-01 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.
