What is immunization

Immunization is the process of conferring

increased resistance

(or decrease susceptibility)

to infection

Page 3: What is immunization Immunization is the process of conferring increased resistance (or decrease susceptibility) to infection.

Immunity and response to antigens

Antigens: any molecule, which can be

recognized by the immune system as being

foreign

The body will respond through innate and

acquired (adaptive) immunity mechanisms to

antigens

Foreign antigens

Innate immunityRapid

Non-specific

No memory

Page 6: What is immunization Immunization is the process of conferring increased resistance (or decrease susceptibility) to infection.

Acquired immunityAntibodies produce in response to an

infection e.g. natural viral infection

Antibodies produced in response to a vaccine

Individuals make their own antibodies

Passive immunityTransfer of maternal antibodies through the

placenta or breast milk

Administration of antibodies collected from

actively immunized humans or animals
