- 2. A type of lymphocyte that assists in the activation of B cells (1,6,4)
- 3. B cells, once activated, can either become plasma cells or the much longer lived ____________ (6,4)
- 4. After many years this type of vaccine is given to remind your immune system how to make antibodies
- 8. Vaccines fall into this category of active immune response
- 9. Faster immune response that occurs when the immune system has been primed for a pathogen
- 11. Slow immune response that occurs when the immune system first meets a pathogen
- 12. Vaccines contain this in order to stimulate the immune system
