Vaccination elicits an immune response which has “memory”

2. Types of Vaccines Attenuated whole-agent vaccines
Contain living but weakened microbes
Inactivated whole-agent vaccines
Contain killed microbes
Toxoids
Inactivated toxins

3. Types of Vaccines Subunit vaccines

Safer than whole-agent vaccines
Conjugated vaccine
Contains a poorly antigenic microbe antigen that is attached to a more antigenic substance

4. Vaccine schedule
