Immunology produced a great advance towards the tip on the nineteenth century, by way of rapid developments while in the research of humoral immunity and cellular immunity.[a hundred ninety] Specifically significant was the function of Paul Ehrlich, who proposed the side-chain theory to clarify the specificity on the antigen-antibody response; his contributions into the idea of humoral immunity were regarded via the award of a joint Nobel Prize in 1908, along with the founding father of cellular immunology, Elie Metchnikoff.

This known as antigenic variation. An example is HIV, which mutates promptly, And so the proteins on its viral envelope which can be important for entry into its host concentrate on cell are continually switching. These frequent adjustments in antigens may well describe the failures of vaccines directed at this virus.
