A Statement of Facts Tending to Establish an Estimate of the True Value and Present State of Vaccination

In Short

This book is a formal medical report and analytical defense of vaccination, written in 1820 to combat the misinformation that plagued early nineteenth-century public health efforts. By comparing historical mortality rates from smallpox across four distinct fifteen-year periods, the author demonstrates that vaccination is the only viable path toward the complete extirpation of the disease. It endures as a vital primary document, capturing both the transformative power of a breakthrough medical discovery and the persistent, irrational human resistance that often accompanies such profound shifts in scientific understanding.

The Story

The narrative begins with a lament for a missed opportunity: twenty-one years have passed since the introduction of vaccination, yet the medical establishment has failed to fully document its success or advocate for its universal application. The author establishes smallpox as the most destructive scourge in human history, noting that while the older method of variolous inoculation saved the individual, it simultaneously served as a vector for spreading the virus to others, ultimately increasing the overall mortality rate.

The heart of the argument lies in a rigorous statistical comparison. By analyzing London’s "bills of mortality" from 1706 through 1818, the author creates four distinct chronological blocks to track the disease’s impact. He meticulously accounts for fluctuations in population and the influence of previous inoculation practices, revealing a sharp, clear decline in smallpox-related deaths once vaccination became a significant force in the early nineteenth century. He calculates that thousands of lives were saved in London alone, despite the interference of skeptics and the continued, reckless practice of variolous inoculation by some medical professionals.

The arc of the argument then moves from the city of London to the global stage. The author highlights the triumph of vaccination in places like Lima, Peru, and various European cities, where the disease was nearly extinguished because the public and local governments embraced the procedure with energy. He addresses the "failures" of vaccination—cases where a vaccinated person might still catch a milder, modified form of the disease—and redefines these as evidence of the vaccine's protective power, arguing that it strips the illness of its lethality, preventing the secondary fevers that historically killed so many.

The story concludes with an appeal to the moral duty of the medical profession and the public. The author argues that the total eradication of smallpox is a practical, achievable goal that is only prevented by human ignorance and the "mischievous publications" of anti-vaccine sentiment. He frames the struggle not merely as a medical disagreement, but as a battle between the enlightenment of scientific progress and the regression of superstition. He calls for the immediate and widespread adoption of the vaccine to finalize a victory that is already within the reach of humanity.

How It Unfolds

The medical gap The author identifies a profound failure within the medical community to properly record the success of vaccination, noting that the records of the Medical and Chirurgical Society remain largely silent on the most important health advancement of the age. He frames the publication as a necessary duty to provide a clear, evidence-based rebuttal to contemporary writers who suggest the value of the discovery is ambiguous.

The statistical proof The narrative shifts to a quantitative analysis, presenting four tables that span over a century of mortality data. By isolating these periods, the author strips away anecdotal evidence and focuses on the objective reality of death rates, showing that mortality shifted significantly only after vaccination became widespread.

The global contrast The author contrasts the hesitation of the English public with the decisive success seen in international locales like Peru and Denmark. These accounts serve as a benchmark for what can be achieved when government and society act in unison to support health initiatives.

The nature of failures A critical section addresses the reality of breakthrough cases, which the author labels "mitigated" or "five-day" smallpox. By distinguishing these mild, non-lethal cases from the true, deadly disease, he effectively disarms the primary argument used by opponents of the practice.

The call to action The conclusion serves as a final, impassioned plea for the total extirpation of the disease. The author insists that England must overcome its internal prejudices to claim the full benefits of a discovery that originated within its own borders.

The People

The book is centered on the ideas and observations of the author, Sir Gilbert Blane, a physician who acts as a rational arbiter of truth. He is motivated by a desire to rectify the "reproach of our country" and to ensure that the medical profession does not abandon a proven life-saving tool due to public clamor. He is a man of the Enlightenment, holding a deep, almost reverent belief that nature’s secrets—once uncovered—must be pursued with scientific rigor for the common good.

Opposing him is the shadow of the "uninformed" and "weak-minded" public, as well as the specific medical detractors like John Birch, whom the author cites for his "mischievous" arguments. Birch represents the institutional inertia and ideological resistance that keeps the public in a state of preventable suffering.

The figure of Edward Jenner stands as the heroic catalyst, the "meritorious discoverer" whose work serves as the foundation for the entire argument. Jenner is rarely mentioned directly as a character, but his presence is felt as the architect of a new era. Finally, the author invokes the anonymous, successful practitioners in places like Peru and Geneva, who serve as models for how a society should function. These people do not struggle with the same political or social resistance found in England, and their swift success highlights the failure of the English medical establishment to adequately champion the cause.

In Its Own Voice

It is now twenty-one years since Vaccination was promulgated in this country by Dr. Jenner, and fifteen years since it began to produce a sensible effect in diminishing the mortality from Small Pox.

This line opens the author’s critique of the medical society's failure to properly document the success of the vaccine.

It is demonstrable, that if at the first moment of this singular discovery, at any moment since, at the present or any future moment, mankind were sufficiently wise and decided to vaccinate the whole of the human species who have not gone through the Small Pox, from that moment would this most loathsome and afflicting of all the scourges of humanity be instantaneously, and for ever, banished from the earth.

The author makes his core argument regarding the total potential of vaccination as an instrument of global health.

What It's Really About

At its core, the book is about the struggle to integrate scientific discovery into a society governed by tradition, fear, and a biased press. It is an argument for the supremacy of empirical data over ideological opinion. The book questions the moral responsibility of the medical practitioner, framing the failure to vaccinate not merely as a clinical oversight but as a "flagitious turpitude." Underlying the analysis is a deep, philosophical belief in human progress; the author views smallpox as an unnecessary, "loathsome" burden that society has the power to shed. Ultimately, the work explores the tension between individual liberty and public safety, arguing that the collective benefit of eradicating a disease far outweighs the "futile and irrelevant" objections raised by those who distrust the process.

Why Read It Today

Readers with an interest in the history of medicine or public health policy will find this book remarkably resonant. It provides a fascinating, unfiltered look at the very early stages of the anti-vaccination movement, proving that the arguments used against public health measures have remained strikingly consistent for over two hundred years. The prose is formal, structured with an eighteenth-century weightiness, and deeply logical; it offers a compelling look at how a scientist navigated the complexities of statistics and public perception in a pre-digital age.

However, the reader should be prepared for the dense, technical nature of the tables and the occasional dry, clinical documentation of mortality rates. The author’s Victorian-era prose can feel long-winded, and his frustration with the "licentiousness" of the press and the ignorance of the common person is on full display. It is not an easy, breezy read, but rather a patient, methodical piece of rhetoric. Those who value the historical process of how medicine moves from an obscure, "rural tradition" to a global standard of care will find this a deeply satisfying, if demanding, primary text. It leaves the reader with a stark reminder of the immense human toll of preventable disease and the enduring power of data to illuminate the path forward.
