Question

question 35 1.67 pts vaccines are effective because they stimulate the development of immunologic memory. inhibit antibodies from having secondary responses. increase the number of natural killer cells while decreasing the numbers of t and b cells. immediately stimulate cellular immunity to eliminate all of the pathogen in the body.

Explanation:

Vaccines introduce antigens that trigger the immune - system to create immunologic memory. This allows for a faster and more effective response upon future exposure to the actual pathogen. Antibodies have secondary responses which are beneficial and vaccines do not inhibit them. Vaccines do not specifically increase natural killer cells while decreasing T and B cells, and they do not immediately eliminate all pathogens.

Answer:

stimulate the development of immunologic memory.
