El pensamiento antivacuna de Alfredo Helsby Hazell: controversias y debates a fines del siglo XIX e inicios del siglo XX en Chile / Alfredo Helsby Hazell's antivaccine view: controversies and debates at the end of the XIX century and the beginning of the XX century in Chile

Resumen El objetivo central de este artículo, es reconstruir los principales argumentos contrarios a la vacunación que circularon en Chile durante fines del siglo XIX e inicios del siglo XX. Para ello, estudiaremos la figura de Alfredo Helsby Hazell, quien fue el principal opositor que tuvo la vacuna en Chile y publicó diversos escritos en los que desarrolló y difundió sus ideas. A través de éstos, observamos que Helsby argumentó su rechazo a la vacunación a partir de la defensa del higienismo y de la desconfianza respecto de las explicaciones de carácter científico que se comenzaron a difundir a partir de la teoría de los gérmenes. Ello se articuló con la defensa de la salud como un ámbito privado de acción, criticando la intervención del Estado en dichas materias.

Abstract This article reconstructs the main arguments against vaccination that circulated in Chile during the late nineteenth and early twentieth centuries. For this purpose, we will study the figure of Alfredo Helsby Hazell, who was the primary opponent of vaccination in Chile and published several writings in which he developed and disseminated his ideas. We observe that Helsby argued his rejection of vaccination from the defence of hygienism and distrust of the scientific explanations that began to spread from the germ theory. This was articulated with the defence of health as a private sphere of action, criticizing the intervention of the State in such matters.

Freedom, Rights, and Vaccine Refusal: The History of an Idea.

We analyzed how activists opposed to vaccination have used arguments related to freedom, liberty, and individual rights in US history. We focused on the period from the 1880s through the 1920s, when the first wave of widespread and sustained antivaccination activism in this country occurred. During this era, activists used the language of liberty and freedom most prominently in opposition to compulsory vaccination laws, which the activists alleged violated their constitutionally protected rights. Critics attacked vaccination with liberty-based arguments even when it was not mandatory, and they used the language of freedom expansively to encompass individuals' freedom to choose their health and medical practices, freedom to raise their children as they saw fit, and freedom from the quasicoercive influence of scientific and medical experts and elite institutions. Evidence suggests that in recent years, vaccine refusal has increasingly been framed as a civil right. We argue that this framing has always lain at the heart of resistance to vaccination and that it may prove consequential for the rollout of COVID-19 vaccines.

The rapid diffusion of the jennerian method was founded in simplicity to practice, in its apparent effectiveness in combating smallpox and its epidemiological opportunity, as it appeared at the time of greatest recrudescence of the disease. The initial impulse for it's propagation, which originated a recognized movement to protect population health, was not without controversy. At the same time that defenders of the vaccine were added, opposite opinions appeared that used diverse critics to discredit it. The most common was to reveal their alleged failures using the media of the time, so cases were reported that occurred in the children of notable people in society. Ignacio María Ruiz de Luzuriaga (1763-1822), as secretary of the Royal Academy of Medicine he assumed a catalytic role, becoming the protagonist of the initial history of vaccination in Spain. It has been considered as an introducer, disseminator and ardent defender of the vaccine, as can be seen from the analysis of the bulky correspondence generated between 1801 and 1802 cataloged as "Papeles sobre la vacuna". These documents, preserved in the Academy library, show their activity as a propagator of the method and its capacity to respond to the doubts and concerns related to their possible adverse effects, avoiding jeopardizing the continuity of vaccines.

La rápida difusión del método jenneriano se cimentó en la sencillez para practicarlo, en su aparente eficacia para combatir las viruelas y en su oportunidad epidemiológica, ya que apareció en el momento de mayor recrudecimiento de la enfermedad. El impulso inicial para su propagación, que originó un reconocido movimiento de protección de la salud poblacional, no estuvo exento de controversia. A la vez que se iban sumando defensores de la vacuna, aparecían opiniones contrarias que utilizaban críticas diversas para desprestigiarla. La más común era divulgar sus supuestos fracasos utilizando los medios de comunicación de la época, para lo que se aireaban casos ocurridos en los hijos de personalidades notables de la sociedad. Ignacio María Ruiz de Luzuriaga (1763-1822), en calidad de secretario de la Real Academia de Medicina Matritense asumió un papel catalizador, convirtiéndose en protagonista de la historia inicial de la vacunación en España. Ha sido considerado como introductor, divulgador y ardiente defensor de la vacuna, tal como se desprende del análisis de la abultada correspondencia que generó entre 1801 y 1802, catalogada como "Papeles sobre la vacuna". Estos documentos, conservados en la biblioteca de la Academia, muestran su actividad como propagador del método y de su capacidad para dar respuesta a las dudas e inquietudes relacionadas con sus posibles efectos adversos, evitando que se pusiera en peligro la continuidad de las vacunaciones.
