The human body is immune to which disease?

  • (A) Jaundice
  • (B) Diabetes
  • (C) Smallpox
  • (D) Tuberculosis
The human body can achieve lifelong immunity to Smallpox after one exposure to the disease or by vaccination. Historically, people who contracted smallpox were recognized to be immune to the disease for life, as their bodies produced long-lasting antibodies against the Variola virus. The smallpox vaccine, the first vaccine in the world, relies on the use of the vaccinia virus to stimulate the immune system to provide lifelong protection against the disease. Due to the fact that immunity to the disease could be achieved on a worldwide scale, smallpox was the first and, to this day, the only human infectious disease officially eradicated by 1980.
