Question 11

What are the two types of acquired immunity? Give examples of all different types

Answer 11

Active acquired immunity (natural active acquired – antibodies. Artificial active acquired – vaccines),
Passive acquired immunity (natural passive acquired – IgG passes from mother’s blood to fetus via placenta, breastmilk. Artificial passive acquired – transferring of antibodies from an immune person to a susceptible person, gamma globulin)
