Case Scenario: Your friend is injured in a car accident and has a laceration (or cut) on her arm. She is transported to the emergency room to receive treatment for the laceration. The physician orders her to be given a tetanus toxoid to protect against tetanus bacteria that could have entered the wound. This will cause an active immune response.
1. Knowing that the tetanus toxoid vaccine has a small amount of tetanus antigens that your friend has not been exposed to before, would her immune response be a primary or secondary response?
2. If she were given a tetanus vaccine (composed of tetanus antigens) again in 10 years, would her immune response be a primary or secondary response?
3. What role do memory cells play in a secondary immune response?
4. Which immune response, primary or secondary, is being described: antibody production begins in 4 days, peak levels are attained in 5 days, and stay at high levels for a long period of time? Need Assignment Help?
5. True or False: When the innate immune system fails to control the pathogens, the adaptive system comes into action. The response of the adaptive immune system is a primary response when it is the first time the cells have encountered the pathogen and a secondary response when the cells have responded to the pathogen in the past.
