After exposure to a novel virus, an infected individual may experience a prolonged period of illness because Question 8 options: immunologic memory cells have a slow response to infection. the primary response is generally stronger than a secondary response. no memory cells to the virus exist, therefore an adequate immunologic response is slow. antibodies to the virus are not being produced. the primary exposure will not elicit an immune response.

The primary immune response Select all that apply occurs more rapidly and is stronger than the secondary response is another name for immunological memory has a lag period while B cells proliferate and differentiate into plasma cells stimulates proliferating B cells to produce some memory cells so that a secondary exposure response will occur faster & stronger

Which of the following statements is true? In the secondary response to an antigen, lower levels of IgM will be detected in an individual's serum. The lag period following secondary exposure to an antigen is longer than the lag period following primary exposure. In the secondary response to an antigen, higher levels of IgM will be detected in an individual's serum. The lag period following secondary exposure to an antigen is shorter than the lag period following primary exposure. An immunocompromised person usually relies on _______ to not become infected by a pathogen because ______. herd immunity; there are too few people in the population susceptible to the pathogen for the disease to spread vaccination; this is the only way the immunocompromised individual can produce antibodies variolation; a small amount of infectious virus will still be eliminated by cytotoxic T cells Which of the following is NOT a class of vaccine? live pathogenic cells inactivated virus pathogen mRNA toxoid
The secondary immune response is: a. slower than the primary immune response b. faster and longer lasting than the primary immune response c. less effective than the primary immune response d. due to the presence of memory cells
