What are antibodies made of?
Passive humoral immunity is acquired by "borrowing" antibodies. How do you borrow antibodies? And why is this form of immunity short term?
Borrow antibodies by vaccine (a shot of antibodies) or by breast-feeding mother. Short term because borrowing does not allow your own body to make memory B cells
How do you acquire active humoral immunity? Why is it long term immunity?
By live vaccines(being injected with a little bit of actual virus) or by being exposed to pathogen (getting sick). Long term because your body responds by making its own memory B cells; so next time you come in contact with that strain of illness your immune system can fight it off.
