- Reduces likelihood epidemics and pandemics occurring through herd immunity.
3
Q
How does vaccinations make us immune to a disease?
A
- patient is injected with a tenuated pathogen or other antigentic material.
- INITIAL ANTIGEN EXPOSURE - clonal selection + clonal expansion happen when antibodies are produced.
- SECONDARY RESPONSE is when the memory cells act. Fast production of large number of antibodies
- no symptoms are shown and a fast recovery is made
4
Q
What routine vaccines are given in childhood?
A
- Polio

6
Q
Why are boosters often needed?
A
- Initial antigen exposure if the first dose
- this elicits the PRIMARY RESPONSE
- CLONAL SELCTION, CLONAL EXPANSIONS, DIFFERENTIATION
- There is only small increase in antibody level meaning that not many memory cells are made.
- Secondary antigen exposure is the booster
- elicts secondary response
- The response is much faster and more antibodies are produced
- more memory cells will remain at the end of the response giving greater immunity against the pathogen.
