Vaccine Revolt

Vaccine Revolt is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vaccine Revolt rather than just read about it. In short: The Vaccine Revolt (Portuguese: Revolta da Vacina) was a popular riot that took place between 10 and 16 November 1904 in the city of Rio de Janeiro, then the capital of Brazil.

Key takeaways

  • Vaccine Revolt belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Vaccine Revolt to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Vaccine Revolt from memory before moving on to harder problems.

Reference excerpt

The Vaccine Revolt (Portuguese: Revolta da Vacina) was a popular riot that took place between 10 and 16 November 1904 in the city of Rio de Janeiro, then the capital of Brazil. Its immediate pretext was a law that made vaccination against smallpox compulsory, but it is also associated with deeper causes, such as the urban reforms being carried out by mayor Pereira Passos and the sanitation campaigns led by physician Oswaldo Cruz. At the beginning of the 20th century, the urban planning of the city of Rio de Janeiro, inherited from a colonial period and the Brazilian Empire, no longer matched its status as a capital and center of economic activities. In addition, the city suffered from serious public health problems. Diseases such as smallpox, bubonic plague and yellow fever ravaged the population and worried the authorities. In order to modernize the city and control such epidemics, president Rodrigues Alves initiated a series of urban and sanitary reforms that changed the city's geography and the daily life of its population. The architectural changes in the city were the responsibility of engineer Pereira Passos, appointed mayor of the then Federal District. Streets were widened, tenements were destroyed and the poor were removed from their former homes. Doctor Oswaldo Cruz, who took over the General Directorate of Public Health in 1903, was responsible for the sanitation campaign in the city, which aimed to eradicate epidemics. To this end, in June 1904, the government proposed a law that made vaccination mandatory. The law generated heated debates between legislators and the population, and, despite a strong opposition campaign, was approved on 31 October. The trigger for the revolt was the publication of a bill to regulate the application of the mandatory vaccine in the newspaper A Notícia, on 9 November 1904. The bill would create a requirement of proof of vaccination for enrollment in schools, obtaining jobs, traveling, getting accommodations, and weddings. It also provided for the imposition of fines on those who resisted vaccination. When the proposal leaked to the press, the indignant and upset people started a series of conflicts and demonstrations that lasted for about a week. Although mandatory vaccination triggered the revolt, protests soon began to target public services in general and government representatives, in particular against repressive forces. A group of florianist and positivist soldiers, with the support of some civil sectors, tried to take advantage of popular discontent to carry out a coup d'état in the early hours of 14 to 15 November, which, however, was defeated. On 16 November, a state of emergency was decreed and mandatory vaccination was suspended. With systematic repression and extinguishment of the triggering cause, the movement ebbed. In the repression that ensued, police forces arrested a number of suspects and individuals considered to be troublemakers, regardless of whether they were involved in the revolt or not. The total balance was 945 people arrested on Ilha das Cobras, 30 dead, 110 injured, and 461 deported to the remote state of Acre.

Background

At the turn of the 19th century, at the same time as the abolitionist movements that put an end to slavery and the monarchy took place, in addition to the revolts that convulsed the first years of the First Brazilian Republic, large contingents of European immigrants and former slaves from the decaying coffee producing zones flocked to Rio de Janeiro, then capital of Brazil. The city underwent a process of industrialization and population growth, rising from 522,651 to 811,444 inhabitants between 1890 and 1906. The pressure for housing led the owners of the large imperial and colonial buildings, which occupied the central region of the city, to divide them internally into several cubicles, transforming them into boarding houses and tenements (cortiços) and renting them out to entire families. The precarious sanitary conditions favored the proliferation of diseases such as the bubonic plague, smallpox and yellow fever, endemic in Rio de Janeiro, especially in the poorest regions. Epidemics gave Rio de Janeiro the reputation of being a plague-ridden and deadly city, driving away foreigners, fearful of contracting diseases, and the urban planning inherited from the colonial period and the Brazilian Empire no longer matched its condition as the capital and center of economic activities in Brazil of that period. In this context, Rodrigues Alves was inaugurated president of Brazil in November 1902. In his first message to Congress, Alves declared that problems in the capital affected and disturbed national development as a whole, and adopted sanitation and improvement of the port of Rio de Janeiro as priorities for his government. Rodrigues Alves had inherited a temporarily stabilized economy from Campos Sales after the Encilhamento crisis, thanks to the recovery of coffee prices on the international market and Sales' austere and unpopular financial policy. Without significantly changing the financial policy of his predecessor, Rodrigues Alves embarked on an intensive program of public works, financed by external resources, which managed to start the economic recovery.

Worked examples

Example 1 — a first encounter with Vaccine Revolt

Start with the simplest possible case. Write down what Vaccine Revolt claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vaccine Revolt before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vaccine Revolt ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vaccine Revolt

In research
Vaccine Revolt appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Vaccine Revolt in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Vaccine Revolt is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1904 in Rio de Janeiro (city), 1904 riots, 20th-century rebellions, so understanding it makes those chapters shorter.
In everyday life
Look for Vaccine Revolt outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
