How important for the prevention of disease was Edward Jenner’s discovery of the smallpox vaccination in 1796? Edward Jenner took the first step in understanding and preventing infectious diseases by developing a smallpox vaccination in the year 1796. This was important as he saved many lives with this new discovery and improved previous methods of preventing disease. Future scientists such as Pasteur and Koch were also able to use Jenner’s work to develop vaccinations for other serious illnesses. However, it was also a limited discovery because it merely tackled one disease and his idea was only gradually accepted by other doctors. The development of the smallpox vaccination was an important discovery because it saved many lives. Jenner observed that milkmaids who contracted the mild disease of cowpox did not seem to catch the more fatal disease of smallpox. To test his hypothesis, Jenner carried out a risky experiment on a healthy eight year old boy by collecting pus from a milkmaid infected with cowpox and transmitting it to the boy’s system via cuts on his skin. Jenner found that the boy fell ill to cowpox but after recovering, he was immune to smallpox thus the method of vaccination was born. This discovery was important as it was an improvement on the previous method of inoculation. Inoculation involved deliberately infecting someone with the desired disease but death rates were extremely high as a result of this practise. However Jenner’s discovery of the smallpox vaccination meant that more lives were saved because there were fewer deaths associated with the vaccination technique and it became more popular than inoculation - eventually becoming a widespread method of disease prevention as it is still in use today. The factors of enquiry and science & technology played an important part in the build up to the development of the smallpox vaccination. On
