immunology

Question 1

vaccines protect against disease by stimulating the production of memory cells

Describe how memory cells protect the baby from disease

Answer 1

1) memory cells carry an immonulogical memory of the specific antigen
2) produces large amounts of plasma cells quickly if the same antigen is encounter a second time

rapid production of antibodies

Question 2

describe and explain the difference in the child’s response to two vaccinations shown in the graph

Answer 2

greater production of antibodies after second vaccination

first encounter takes time for B cells to become activated/ clone

so there is a time delay before antibodies can be produced

memory cells present as results of first vaccination

Question 3

difference between active and passive immunity

Answer 3

1. antibodies not produced in passive immunity

2. no memory cells in passive immunity
