The smallpox vaccine, the world's first vaccine, was developed in 1796 by British physician Edward Jenner. The smallpox vaccine was used to prevent smallpox infection caused by the variola virus and has saved more human lives than any other medical invention in history. The development of the smallpox vaccine led to the global eradication of smallpox, the only human disease to be eradicated. This paved the way for further vaccination campaigns, such as the World Health Organization's (WHO) Global Polio Eradication Initiative launched in 1988. The smallpox vaccine also contributed to advancements in laboratory techniques for creating vaccines in the 19th century by Louis Pasteur.

What You'll Learn
The smallpox vaccine was the first of its kind
For centuries, smallpox wreaked havoc on mankind, leaving devastation in its wake. The development of the smallpox vaccine was a groundbreaking achievement, offering protection against this deadly disease and changing the course of history.
The origins of the smallpox vaccine can be traced back to the observations of English physician Edward Jenner in 1796. Jenner noticed that milkmaids who had contracted cowpox, a mild bovine virus, seemed to be immune to smallpox. This led him to postulate that exposure to cowpox could confer immunity against smallpox. To test his theory, Jenner inoculated his patient, Phipps, with matter from a human smallpox sore, and Phipps subsequently remained in perfect health, becoming the first person to be vaccinated against smallpox.
The term "vaccine" itself is derived from the Latin word "vacca," meaning cow, reflecting the role of cowpox in the development of the smallpox vaccine. Jenner's discovery was met with a mixed reaction in the medical community, but it laid the foundation for future vaccine development and global immunization efforts.
The success of the smallpox vaccine led to mandatory vaccination campaigns in Britain, the United States, and other parts of the world in the 1840s and 1850s. This was followed by universal childhood immunization programs and mass vaccination drives, which played a crucial role in eradicating smallpox. In 1958, the World Health Organization (WHO) launched a global smallpox eradication campaign, and by 1977, smallpox was officially eradicated, becoming the only human disease to be eliminated worldwide.

The vaccine's development was influenced by West African techniques
The smallpox vaccine was influenced by West African techniques that had been practised for centuries. Enslaved West Africans had long practised a form of inoculation, and in 1716, Cotton Mather publicised this technique, advocating for its use during a 1721 smallpox outbreak in Massachusetts. This technique, known as variolation, involved the subcutaneous instillation of smallpox into non-immune individuals.
In 1796, British physician Edward Jenner demonstrated that infection with the mild cowpox virus conferred immunity against smallpox. This discovery led to the development of the world's first vaccine, using the same principle as variolation but with the less dangerous cowpox virus. The term "vaccine" is derived from the Latin word for cow, "vacca", reflecting the origins of smallpox vaccination.
Jenner's work built upon the knowledge shared by enslaved West Africans, who had a long history of practising variolation. This exchange of knowledge between communities played a crucial role in the development of the smallpox vaccine, which eventually led to the eradication of smallpox as a global disease.
The impact of the smallpox vaccine extended beyond the specific disease it targeted. It paved the way for advancements in immunisation and vaccination technologies, influencing the development of subsequent vaccines such as those for yellow fever, whooping cough, and polio. The success of the smallpox vaccine also highlighted the importance of universal childhood immunisation programmes, mass vaccination campaigns, and targeted surveillance-containment strategies in disease eradication efforts.
While the development of the smallpox vaccine was a significant milestone, it is important to acknowledge the complex history of vaccination in West Africa. The region has been a target of anti-vaccine disinformation and conspiracy theories, often originating from North America and spreading through online platforms. Additionally, historical incidents of "medical colonialism" have contributed to negative vaccine narratives in West Africa, impacting trust in institutions and shaping the collective psyche of the region.

The vaccine's development was influenced by variolation
The development of the smallpox vaccine was influenced by the ancient practice of variolation, also known as inoculation. Variolation was first introduced in Europe by Lady Mary Wortley Montagu in 1721, after she observed the practice in the Ottoman Empire. It was also publicised in 1716 by Cotton Mather, who learned about the technique from enslaved West Africans.
Variolation was a method of immunisation against smallpox that involved transferring material from a patient with smallpox or a recently variolated individual to a healthy person. This was done by inserting or rubbing powdered smallpox scabs or fluid from pustules into scratches made in the skin. The hope was that this would induce a mild but protective infection, and indeed, only 1-2% of those variolated died from the intentional infection compared to 30% who contracted smallpox naturally.
The method of variolation was first used in China, India, parts of Africa, and the Middle East before it was introduced to England and North America in the 1720s. In China, smallpox scabs were dried and ground before being blown into the nostril using a pipe, while in India, a lancet or needle was used to transfer material from smallpox pustules to the skin.
While variolation was a significant advancement in the fight against smallpox, it was not without its risks. It was eventually replaced by the smallpox vaccine, a safer alternative discovered by Edward Jenner in 1796. Jenner's vaccine used the same principle as variolation but with a less dangerous viral source, cowpox. This discovery revolutionised the control of smallpox and led to the development of many other vaccines against diseases such as diphtheria, measles, mumps, rubella, and influenza.

The vaccine's development was influenced by observations of milkmaids
The development of the smallpox vaccine was influenced by observations of milkmaids. In 1796, English physician Edward Jenner noticed that milkmaids who had been infected with cowpox were protected from smallpox. This led him to create the world's first successful vaccine, using the same principle as variolation but with the less dangerous cowpox virus.
Jenner's discovery was the result of his observation that milkmaids, renowned for their beauty, seemed to be immune to smallpox. At a time when smallpox was endemic and often left survivors with scars, Jenner noticed that milkmaids always seemed to escape this dermatological blight. This sparked his curiosity, and he set out to understand why these women were protected from the disease.
Jenner's hypothesis was that infection with cowpox, a bovine virus that could spread to humans, could protect a person from smallpox. To test this hypothesis, Jenner inoculated his patient, Phipps, with matter from a human smallpox sore in July 1796. Phipps remained in perfect health and became the first person to be vaccinated against smallpox.
Jenner's discovery was a breakthrough in the fight against smallpox, a disease that had devastated mankind for centuries. His work laid the foundation for the development of vaccines, which have saved more human lives than any other medical invention in history. The term "vaccine" itself is derived from the Latin word "vacca," meaning cow, reflecting the origins of smallpox vaccination in cowpox infection.
Following Jenner's discovery, the smallpox vaccine was refined and perfected over centuries by countless researchers. The Intensified Eradication Program, launched in 1967, further contributed to the global efforts to eradicate smallpox. This program addressed the challenges of previous campaigns, resulting in the production of higher-quality freeze-dried vaccines in greater quantities.

The smallpox vaccine led to global eradication initiatives
The smallpox vaccine, the world's first vaccine, was developed in 1796 by British physician Edward Jenner. Jenner observed that milkmaids who had contracted cowpox were protected from smallpox. He inoculated James Phipps with matter from a human smallpox sore, and Phipps remained in perfect health, becoming the first person to be vaccinated against smallpox.
The development of the smallpox vaccine led to a global eradication initiative. In 1958, the World Health Organization (WHO) launched a global vaccination campaign to eradicate smallpox. This campaign faced challenges due to a lack of resources and commitment from countries. However, with renewed efforts starting in 1967, the Intensified Eradication Program was able to produce more high-quality freeze-dried vaccines.
The global eradication campaign involved universal childhood immunization programs, mass vaccination drives, and targeted surveillance-containment strategies. In 1977, the WHO successfully eradicated smallpox, making it the only human disease to be eliminated. This remarkable achievement demonstrated the power of vaccines and set a precedent for global health initiatives.
Following the success of the smallpox eradication program, the WHO turned its attention to poliomyelitis in 1988, launching the Global Polio Eradication Initiative. This initiative aimed to eradicate polio worldwide by the year 2000. By 1994, polio was eradicated from the Americas, and Europe followed in 2002. The fight against polio continues, and the efforts inspired by the smallpox vaccine's success have saved countless lives and improved global health outcomes.
The smallpox vaccine not only protected people from a deadly disease but also paved the way for global health initiatives aimed at eradicating other diseases. It demonstrated the effectiveness of vaccines and the importance of universal immunization programs. The legacy of the smallpox vaccine lives on in the ongoing fight against infectious diseases and the development of new vaccines to protect humanity.
