- Artificial Passive
- The Immune Response
- Primary
- Phagocytosis
- Antigens on surface of pathogen trigger immune response
- Phagocyte merges membrane and engulfs pathogen
- Lysosome releases enzyme into phagocytic vacuole
- Pathogen is hydrolysed
- Antigens are presented on phagocyte
- Pathogen is hydrolysed
- Lysosome releases enzyme into phagocytic vacuole
- Phagocyte merges membrane and engulfs pathogen
- Antigens on surface of pathogen trigger immune response
- T-Cell Activation
- Cytotoxic T-Cells kill abnormal cells
- Helper T-Cells release signals to stimulate phagocytes
- B-Cell Activation
- Bind to antigen presented on T-Cell to find comple-mentary fit
- Produce plasma cells with identical antibodies
- Bind to antigen presented on T-Cell to find comple-mentary fit
- Phagocytosis
- Secondary
- Memory T and B-Cells
- Replicate quickly
- Memory T and B-Cells
- Primary
- Ethics
- Who should receive the vaccine first if a pandemic occurs?
- Animal Testing
- People who don't take the vaccine- not fair?
- Vaccination
