Problem 9

Question

After Jen punctured her hand with a muddy nail, in the emergency room she received both a vaccine and someone else's antibodies against tetanus toxin. The immunity conferred here is: a. both active and passive. b. active only. c. passive only. d. first active; later passive. e. innate.

Step-by-Step Solution

Verified
Answer
a. both active and passive.
1Step 1: Understand Active Immunity
Active immunity refers to the process where the body's immune system responds to antigens by producing antibodies. It's a longer-term and requires time to develop. Here, Immunization by way of administration of a vaccine stimulates this type of immunity.
2Step 2: Understand Passive Immunity
Passive immunity refers to the process where antibodies are transferred from one individual to another. It provides immediate, but short-term immunity. The example here is the transfer of antibodies against tetanus toxin from another person.
3Step 3: Make the Conclusion
Considering the factors of active immunity (administration of vaccine) and passive immunity (transfer of antibodies from someone else), Jen has received both types of immunities.
