Edward Jenner and Smallpox Vaccine

Play an AI-generated podcast conversation about this lesson

Which factor most significantly contributed to Edward Jenner's understanding of immunology and eventual development of the smallpox vaccine?

His independent study of ancient texts on medicine and natural philosophy, guiding his approach to disease and immunity.

His family's long-standing tradition in medicine, granting him access to a wealth of historical medical knowledge.

His early experience contracting smallpox, coupled with later illness after variolation, providing first-hand insight into the disease and its prevention. (correct)

His extensive travels across Europe, exposing him to diverse medical practices and epidemiological patterns.

Edward Jenner faced considerable skepticism and resistance despite the success of his smallpox vaccination. Which factor most likely contributed to this initial resistance?

The concept of deliberately infecting individuals with a related disease, cowpox, was counterintuitive and raised ethical concerns at the time. (correct)

The Royal Society openly disputed Jenner's findings, influencing the medical community's rejection of his work.

Jenner's work was primarily theoretical, lacking empirical evidence from controlled clinical trials.

Jenner's report was published in obscure journals, limiting its reach and impact on the broader scientific community.

What was the key difference between variolation and Jenner's vaccination technique, in terms of methodology and risk?

Variolation involved administering weakened smallpox virus, while vaccination used a completely different virus (cowpox).

Variolation involved direct injection into the bloodstream, while vaccination was administered topically.

Variolation required multiple applications over a long period, while vaccination was a one-time procedure for lifetime immunity.

Variolation used live smallpox virus, carrying a risk of severe infection or death, whereas vaccination used cowpox, which induced immunity with minimal risk. (correct)
