Part B We now know that cowpox and smallpox have similar antigens. How does this fact explain why exposure to cowpox enables a person to develop immunity to smallpox? The high variability of cowpox antigens trains the immune system to recognize antigens of many viruses. The antigens on cowpox can be used to develop antibiotics that target smallpox. Memory cells created in the adaptive immune response to cowpox recognize smallpox antigens due to their similarity. The innate immune response to cowpox leads to smallpox immunity due to their similar antigens.

The smallpox vaccine was somewhat temperature sensitive, so for a while, in certain parts of the world, they would perform person to person transmission by using the pustules that form from the original inoculation with vaccinia virus. Please describe reason(s) why, other than smallpox vaccination, that sharing pustule fluid and often blood from one person to the next could cause other health concerns.
