• the white blood cells reproduce rapidly.

Vaccination provides immunity to specific diseases. Why are vaccines referred to as a form of artificial active immunity?

• They are attenuated forms of the pathogen

• They lead to the production of memory cells

• They involve deliberate exposure to antigenic material to stimulate an immune response

• The vaccines are produced through artificial means
