Like all science, Immunology has developed Edward Jenner
through the work of many doctors and
research scientists. This person developed a
protocol to protect people from the Small
Pox virus, he called the protocol Vaccination
due to the fact it involved the Vaccinia virus.

animals. What diseases did they use in their
experiments (select all that are correct).

T cells kill cells infected with a virus.
B cells release antibodies.
Sensory cells release cytokines and
