*

Injection of cellular material to induce immunity. From the latin word ‘vacca’ means cow. It is the act of introducing vaccine into the body to provide protection from a specific dse; much safer and effective than variolation. Six millennia (600 years) before the vaccine for smallpox was created.

Q

are not too different; it happens simultaneously in the body.
➔ Both are significant in successful immune
responses.
➔ Both are dependent upon each other, and
operate in combination.
➔ Ex. bacteria free floating in the blood when
macrophage see it can eat easily but sometimes macrophage is confused now the humoral immunity will help by releasing opsonins (opsonins coat non-self-antigen making macrophage eat in few seconds)
