1
Q
How can Immunity be developed?
A
By vaccination using antigens from infectious pathogens
2
Q
What are the antigens used in vaccines?
A
Inactivated pathogen toxins, dead pathogens, weakened pathogens
3
Q
What is the primary immune response?
A
B lymphocytes producing antibodies
4
Q
What is the secondary immune response?
A
Memory cells remain in the body if we eber come across the pathogen again
5
Q
What are antigens mixed with?
A
Adjuvants
6
Q
What are adjuvants?
A
Substance that makes the vaccines more effective by enhancing the immune response
7
Q
What is antigenic variation?
A
Pathogens can change their antigens so that antibodies and memory cells are not effective against them
