He Could Not Give the Shot

What this is about

In 1885 a nine-year-old boy was brought to a laboratory in Paris. Inside was a method that had been tested on fifty dogs and had never been used on a person (PMID 34322641).

The heart of this story is not "he did it anyway." Pasteur was not a physician. He had no standing to put a needle into a human body, and the thirteen shots were given by a young paediatrician, Joseph Grancher (PMID 37310124).

The boy lived. But failures followed, and the person who defended the treatment before the medical establishment was Grancher, not Pasteur (DOI: 10.1353/bhm.2002.0176).

This edition is about how people got through a moment where doing nothing means death and doing something means acting on what nobody has verified — and what rules were built afterwards.

What actually happened

• Louis Pasteur (1822–1895) held doctorates in chemistry and physics, moved through work on fermentation, and developed pasteurization in 1864 (PMID 37310124). Then he took on a very old disease: rabies (PMID 41401337).
• Rabies begins at the bite. The virus sits quietly in muscle, enters the peripheral nerves at the neuromuscular junction, and travels back up the nerves to the brain (DOI: 10.3389/fimmu.2021.786953). Once it reaches the brain the case-fatality rate is close to 100% (PMID 30747146).
• That is why there is time. Even the modern vaccine only works if it is given before the virus reaches the brain — and it saves more than 250,000 people every year (DOI: 10.20944/preprints202208.0531.v1).
• In 1885 Pasteur revealed that he had already immunised fifty dogs against rabies. He was looking for human subjects (PMID 34322641).
• That same year, nine-year-old Joseph Meister received thirteen injections. Grancher gave them. In the laboratory his key colleague was Émile Roux, and among the clinicians who defended the technique at the Academy was Alfred Vulpian (PMID 34322641). Pasteur and his colleagues at the École Normale Supérieure were not physicians but scientists, which is why almost all the work up to that point had been done in animals (PMID 37310124).
• The opposition was real. Getting his findings accepted by the French medical community was difficult (PMID 36852598), and his rival Robert Koch pointed to the great ambiguity in how Pasteur prepared his vaccines (PMID 35454184).
• On 11 January 1887, at the National Academy of Medicine, Michel Peter charged that the method could be dangerous and had been fatal in certain cases, and Grancher defended it — arguing that risk is inherent in all medical therapy. A study of the unpublished correspondence also notes the suppression of autopsy evidence in one fatal case (DOI: 10.1353/bhm.2002.0176).
• The Pasteur Institute opened in Paris in 1888. But the first Pasteur Institute was in Rio de Janeiro, nine months earlier, funded by the Brazilian emperor Dom Pedro II (PMID 37310124, PMID 34322641).

Questions your child may ask

"If it doesn't hurt right away, why is it dangerous?" That is the shape of the disease. The virus climbs the nerves toward the brain very slowly, and during that time you feel fine (DOI: 10.3389/fimmu.2021.786953). Once it arrives, nothing can be done. That slow journey is the only gap in which a vaccine can win.

"Pasteur wasn't a doctor?" He was not. He and his colleagues were scientists, not physicians, so nearly all their work was in animals (PMID 37310124). For a child: "The person who worked it out and the person allowed to do it to a human being were not the same person."

"So there were no rules back then?" Not the rules we have now. That is why this treatment has been ethically criticised and disputed from then until now (PMID 37310124). One study frames the whole development as a collision between usefulness to the public and individual autonomy (PMID 34322641).

"Did everyone get better afterwards?" No. Some people died despite the treatment, and that was the core of the 1887 dispute (DOI: 10.1353/bhm.2002.0176). Leave this out and the story becomes a lie.

"Can people still get rabies?" Dog vaccination has eliminated rabies in terrestrial carnivores across Western Europe and most of North America. Even so, about 59,000 people die every year (PMID 30747146), and 99% of human rabies deaths come from dog bites (DOI: 10.52768/2766-7820/1296). Children in rural Asia and Africa are hit hardest (PMID 32454001).

The hard part — consent and clinical trials (for parents)

Do not soften this. Translated into today's terms, 1885 looks like this: an unverified treatment supported only by animal data was used on a nine-year-old child with no prior review. Pasteur had his fifty-dog result and was looking for human subjects (PMID 34322641). The intervention remains ethically disputed today (PMID 37310124).

The fact on the other side is equally plain: do nothing, and the case-fatality rate after onset is close to 100% (PMID 30747146). This is not "a bad man did a bad thing." It is a story about a situation where both options are bad.

That is where today's machinery comes from.

• Trial phases — animals → safety in a small number of people → efficacy → large comparisons, in that order. In 1885 that ladder did not exist.
• Prior review — an independent committee reads the protocol first. It exists to break the structure in which the researcher decides for himself that it is fine.
• Informed consent — the risks are explained and refusal is protected. For children, a guardian's consent plus the child's own assent (PMID 34322641).
• Publishing unfavourable results — the 1887 defence involved the suppression of autopsy evidence (DOI: 10.1353/bhm.2002.0176). Trial pre-registration and mandatory adverse-event reporting exist to block exactly that temptation.

One line is enough for a child: "Back then there was no rule about asking. Now there is. People made that rule after things like this."

Ideas inside the story

• Treatment as a race — the rabies vaccine does not beat the disease; it arrives before the virus reaches the brain.
• Discovery and authority are separable — the one who finds it may not be the one allowed to do it.
• Rules come afterwards — consent and review were built out of argument and failure, not present from the start.

What is evidence and what is story

Straight from the literature Nine years old, thirteen injections, 1885, given by the young paediatrician Grancher, Pasteur and his colleagues being scientists rather than physicians, and the intervention being ethically criticised and disputed (PMID 37310124). The fifty dogs and "looking for human subjects" (PMID 34322641). The Peter–Grancher exchange of 11 January 1887 and the suppressed autopsy evidence (DOI: 10.1353/bhm.2002.0176).

Deliberately left out Widely repeated details that this source set does not confirm were not used: that the boy came with his mother, the exact date, the circumstances of the dog, and the claim that Pasteur agonised through the night. The last one is the most tempting, because it makes the story comfortable by suggesting he hesitated too. What this edition can speak to is not his mind but his standing and the procedure.

A date discrepancy Most sources put the Meister treatment in 1885; one textbook chapter dates the introduction of the human rabies vaccine to 1884 (DOI: 10.1093/hesc/9780198714682.003.0019). This edition follows the majority.

Contested reading Assessments of the man differ. After his notebooks were opened, historians worked to separate the legend built by his hagiographers from the reality (PMID 35454184, PMID 39347279), and there are papers pushing back on that re-evaluation (DOI: 10.1002/chir.23049). This edition builds its narrative only from what several sources record in common.

Sources and what followed

Main sources — PMID 37310124 (Meister, Grancher), PMID 34322641 (fifty dogs, autonomy), DOI: 10.1353/bhm.2002.0176 (the 1887 defence), DOI: 10.3389/fimmu.2021.786953 (pathogenesis), PMID 30747146 (fatality), PMID 35454184 · PMID 39347279 (myth and reality), PMID 8804019 (Negri bodies).

What followed

• Diagnosis arrived. In 1903 Adelchi Negri found distinctive inclusion bodies in neurons of infected brains, and they became a diagnostic tool in anti-rabies institutes worldwide. The study that settled their diagnostic value was done in 1913 by his wife, Lina Negri-Luzzani (PMID 8804019, PMID 32454001).
• Blocking the animal side turned out to work better. Mass dog vaccination and oral vaccines for wildlife eliminated rabies in terrestrial carnivores across most of Western Europe and North America (PMID 30747146).
• It is not over. About 59,000 people die each year (PMID 30747146), mostly where dog vaccination is hard to deliver, and mostly rural children (PMID 32454001).

Things to do together

• Decide in advance what to do after a bite or scratch: tell an adult immediately → wash long with running water and soap → clinic.
• Pick between two bad options. Invent a situation where doing nothing is clearly bad and doing something has an unknown outcome. The point is not the answer; it is for the child to learn that adults do not know the answer in moments like this either.
• Keep an "did you ask first?" rule for one day. Ask before doing something for someone. It is the fastest way to feel what informed consent means.
