What is true of a secondary immune response?
- It is brought about by memory cells
- It is weaker than a primary immune response.
- It can involve B-cells but not T-cells
- It is faster than a primary immune response
- After it occurs, the immune system can only respond to reinfection with the same antigen by mounting another primary immune response

The goal of vaccinations is to generate memory lymphocytes that will protect you from disease if you subsequently encounter one of the pathogens that you were vaccinated against. Which two of the following are true statements about how vaccines work? 1. some vaccines are designed to generate memory B cells, others are designed to generate memory T cells, and some will generate both memory B cells and memory T cells 2. the secondary immune responses generated by vaccination are called...

All of the following may be targeted by TC cells, except Multiple Choice viral-infected host cells. cancer cells. invading bacterial cells. cells in transplanted tissue from an imperfectly matched donor. All of these cells could be targeted by Tc cells. 2. Primary and secondary antibody response differ in all the following ways, except Multiple Choice IgG production predominates in secondary responses. the lag period between antigen stimulation and antibody response is shorter in the secondary response. the rate of...
