Antibodies given directly, short lasting immunity, no memory cell production
Naturally acquired - across placenta
Artificial - snake anti venom
3

MMR
Whole virus, reduced virulence
Gives lifelong immunity but can cause some problems
4
What is an inactivated vaccine? Give an example

Tetanus
Injection of toxin that causes the disease
No protection against pathogen itself
7
What is a conjugate vaccine? Give an example
Pneumococcus
Binding of a weak antigen to a strong antigen
Causes response to the weak antigen to be bigger
8
