RESUMO
Se relata el nacimiento, auge y decadencia, de la producción de vacunas en el antiguo Instituto Bacteriológico de Chile, desde su fundación en 1929 hasta su fin en 1980, por boca de quien fuera por diecisiete años primero encargado de la fabricación de vacunas bacterianas y luego director de la institución. Las vicisitudes de la vacuna BCG, la introducción del toxoide tetánico, el fin de la vacuna antivariólica y el triunfo de vacuna antirrábica de Fuenzalida y Palacios, se narran a menudo con comentarios de quienes participaron en estos hechos.
The birth, rise and decline, of vaccine production at the Bacteriological Institute of Chile is recounted by mouth of who was for seventeen years first in charge of manufacturing and then director of the institution. The vicissitudes of the BCG vaccine, the introduction of tetanus toxoid, the end of smallpox vaccine, and the triumph of the rabies vaccine are often related with comments from those who participated in the events.

Tuberculosis currently remains a serious medical problem, therefore increased attention is being paid to this disease. Paleopathological studies focused on the monitoring of morbid changes in skeletal remains of historical populations facilitate a detailed study of the development of this disease. They provide direct evidence of the existence of tuberculosis and its past forms. In addition to literary and iconographic sources, the present study is focused on recording the findings of bone tuberculosis in historical osteological sets from the Czech Lands and is the starting point for their detailed review. Approximately 76 cases of bone tuberculosis from the Czech Lands have been published and more or less reliably documented from 20 archeological sites dated back from the Eneolithic to the modern period.

Reconstructing some of the experiences of people living with tuberculosis in Argentina in the first half of the twentieth century, as reflected not only in written and oral accounts but also in individual and collective actions, this article explores the ways in which patients came to grips with medical expertise in times of biomedical uncertainty. These negotiations, which inevitably included adaptations as well as confrontations, highlight a much less passive and submissive patient-physician relationship than is often assumed. Though patients were certainly subordinate to medical doctors' knowledge and practices, that subordination, far from absolute, was limited and often overthrown. The article focuses on patients' demands to gain access to a vaccine not approved by the medical establishment. By engaging with media organizations, the sick invoked their "right to health" in order to obtain access to experimental treatments when biomedicine was unable to deliver efficient therapies.

As physicians, we've all learned in detail about the science behind vaccinations, but I suspect few of us have been taught about the history of vaccinations. Sure, we all know that Dr. Jonas Salk developed the poliovirus vaccine, but I wasn't aware that he inoculated himself, his wife, and his three children with his then experimental vaccine. When our editorial committee decided to focus on vaccinations as our theme for this month's Greene County Medical Society's Journal, I perused the internet for interesting topics. I came across a fascinating website, historyofvaccines.org; this website is a project of the College of Physicians of Philadelphia, touted as being the oldest professional medical organization in the United States. I credit the majority of the information in this article to the above website and the rest to the National Institutes of Health (nih.gov) website; I trust that the information is valid and true, based on the agencies behind these websites. Below are some interesting tidbits about vaccine preventable diseases that I found noteworthy to pass on to our readers.

The use of animal models has been invaluable for studying the pathogenesis of Mycobacterium tuberculosis infection, as well as for testing the efficacy of vaccines and drug regimens for tuberculosis. Among the applied animal models, nonhuman primates, particularly macaques, share the greatest anatomical and physiological similarities with humans. As such, macaque models have been used for investigating tuberculosis pathogenesis and preclinical testing of drugs and vaccines. This review focuses on published major studies which illustrate how the rhesus and cynomolgus macaques have enriched and may continue to advance the field of global tuberculosis research.

The current tuberculosis (TB) vaccine bacillus Calmette-Guérin (BCG) fails to protect against adult pulmonary TB. Yet, its capacity to control miliary TB in newborn infants forms the basis for development of novel vaccine candidates. These either exploit genetic modification of BCG to create a viable replacement vaccine or use BCG to prime the immune response followed by boost with a novel subunit vaccine. This could ultimately result in a combination vaccination schedule comprising a prime with a live BCG replacement followed by a subunit vaccine boost. Ultimately, vaccination strategies that achieve sterile eradication of, or prevent infection with, tubercle bacilli would be an ambitious highly promising goal.

Developing effective prophylactics to combat tuberculosis is currently in an exploratory stage. The HIV pandemic and emergence of multi- and extensively drug-resistant strains of Mycobacterium tuberculosis indicate that the current preventive measures against this ever-evolving pathogen are inadequate. The currently available vaccine BCG in its present form affords variable protection which usually wanes with aging. Various reasons have been cited to explain the discrepancies in the efficacy of BCG, including generic differences in the different BCG vaccine strains used in immunization program throughout the world. The low efficacy of BCG vaccine has promoted the search for novel vaccines for tuberculosis. The search strategies aim at completely replacing the existing vaccine and/or augmenting/improving the current BCG vaccine. Among new vaccine candidates are live attenuated M. tuberculosis vaccines, recombinant BCG, DNA vaccines, subunit vaccine, and fusion protein-based vaccines. More than 200 new vaccine candidates have been developed as a result of research work over the past few years. To date, at least eight vaccine candidates are undergoing clinical evaluation, with a few of them successfully qualifying in the first phase of clinical testing. These recent advances present an optimistic insight whereby a new tuberculosis vaccine might be expected to be available for public use in the next few years.

The use of tuberculin for the therapy of tuberculosis was attempted more than 100 years ago and abandoned because of its adverse reactions. In this historical review we point out that some of the intensive efforts to avoid the reactions were based on the best scientific rationale available at that time. Balancing the dosage and intervals of tuberculin delivery with clinical and laboratory monitoring of patients achieved a limited success, with implications, toward current research in the field. The role of economical and social aspects at that time is also a lesson to be learned toward current approaches to tuberculosis control.

The design of tuberculosis vaccines has entered a new era. Although several new vaccine candidates will pass Phase I clinical trials within the next year, I believe that the most effective vaccination strategy will be to combine different vaccine candidates and to use a prime-boost approach. This strategy, however, would require several years of iterative vaccine trials, unless the process is expedited by the identification of reliable biomarkers for assessing vaccine efficacy. In this Essay, I briefly summarize past and present attempts to develop a vaccine against tuberculosis, and I describe, using imagined scenarios, the tuberculosis vaccination schemes that might become available from a large repertoire of candidate schemes in the near and distant future.

Realizamos una revisión histórica de la tuberculosis, enfermedad que durante siglos supuso uno de los mayores azotes que sufrió la humanidad, lo que hizo que en la Edad Media fuera conocida como la peste blanca. Su epidemiología refleja el carácter social de esta enfermedad, considerada por algunos autores, todavía a comienzos del siglo XX, la más mortífera en los países civilizados. Se revisan, asimismo, los criterios mantenidos en la lucha contra la tuberculosis y, especialmente, el tratamiento médico y quirúrgico utilizado hasta el descubrimiento de la estreptomicina, que cambió radicalmente su pronóstico. El artículo aporta iconografía alusiva a figuras relevantes, acontecimientos y otros aspectos relacionados con la enfermedad
We have made a historic account of tuberculosis. Tuberculosis was one of the greatest calamities that afflicted Humanity for centuries which made this disease to be known as the White Plague in the Middle Ages. Its epidemiology reflects the social character of this condition and it was considered by some authors as late as the beginning the XX century, as the most deadly one in the civilized world. At the same time, we revise the different criteria kept in the fight against tuberculosis. Special attention is paid to the c1inical and surgical treatments used until the appearance of streptomycin. The discovery of streptomycin brought a dramatic change to the prognosis of those affected by tuberculosis. This artic1e contributes to widen the iconography of relevant figures related to the field, as well as to the presentation and discussion of events and other aspects in relation to tuberculosis

The Royal Dutch Tuberculosis Association (Koninklijke Nederlandse Centrale Vereniging tot bestrijding der Tuberculose (KNCV)) was founded in 1903. Since then various interventions against tuberculosis have been introduced on the basis of medical and technological opportunities and in response to the epidemiological situation. The introduction of effective drugs during the 1940s and 1950s was by far the most important development and led to a sharp decline in the annual rate of infection and to the disappearance of tuberculosis as a common disease. Following the appointment of the independent National Policy Committee for Tuberculosis Control, Royal Dutch Tuberculosis Association could concentrate on its innovating tasks: the development of new interventions based on epidemiological data and scientific research.

Tuberculosis still remains a leading infectious cause of death worldwide, although the BCG vaccine has been used for 80 years. There is an urgent need to develop improved BCG or new tuberculosis vaccines. This apparently represents a daunting task, since it will take a long time before a vaccine can be declared to be better than the current BCG vaccine, both in experimental and human studies. The current review takes a brief historic look at the use of current BCG vaccine and provides an overview on what are considered to be the key immunologic criteria that have to be met by a new generation of tuberculosis vaccines. It also provides the most up-to-date information on the latest developments in tuberculosis vaccine research, with a focus on mycobacterial organism-based and Mycobacterium tuberculosis antigen-based vaccines. Consideration is also given to the mucosal route of immunization and 'prime and boost' regimens. This review also presents several important tables, highlighting critical components of antituberculosis immunity, the most commonly tested immune adjuvants, the types of novel tuberculosis antigen-based vaccines and the outcome of different heterologous 'prime and boost' vaccination regimens.
