The first vaccine to be used successfully was a vaccine against smallpox, a terrible disease that killed 30% of people that it infected and ended up killing hundreds of millions throughout history. Those earlier vaccinations relied on injecting small doses of the virus into healthy patients to build their immune systems against the disease. But the inspiration came from a practice that was done already for hundreds of years in the Byzantine Empire, and thanks to the courage of one woman.
Lady Mary Wortley Montagu was an English aristocrat who, in the early 18th century, moved to the Ottoman Empire when her husband was appointed as the Ambassador. This led her to reside in Constantinople (modern-day Istanbul). During her stay in the Ottoman Empire, she came across variolation, an early method of immunization against smallpox. Variolation involves intentionally introducing smallpox matter into the skin of a non-immune individual. Montagu was particularly impressed by this practice, as it proved successful in inducing immunity against the devastating disease that had already claimed the life of her brother and left her scarred.
After returning to England, Lady Montagu became an ardent supporter of variolation, despite facing opposition from the medical community and society as a whole. She was determined to prove the effectiveness and safety of the procedure. In 1721, she had her own daughter variolated, which was a highly controversial and risky act at that time. However, her conviction in the procedure's benefits eventually gained the attention and support of some physicians. As a result, the practice of variolation began to spread across England and later throughout Europe. This laid the foundation for the future development of vaccines in 1796.
This story highlights the significance of learning from diverse cultures, especially in the field of medicine. The practice of inoculation, which was introduced to the West by the Ottoman Empire, established the foundation for vaccine development. This exemplifies how collaborative and inclusive viewpoints can drive scientific progress and enhance global health outcomes. Embracing knowledge from all over the world continues to encourage innovations that propel humanity forward, reminding us that progress often results from the assimilation of diverse ideas and traditions.
