Verified step by step guidance

Understand the concept of active artificially acquired immunity. This type of immunity involves the introduction of antigens into the body through medical intervention, rather than natural exposure.

Recognize that vaccination is a process where a weakened or inactive form of a pathogen is introduced into the body to stimulate the immune system to produce antibodies.

Differentiate between active and passive immunity. Active immunity involves the body's direct response to the pathogen, while passive immunity involves receiving antibodies from another source.

Consider the options provided: vaccination, contact with a pathogen, contact with toxins, antibodies from mother to fetus, and antibodies from mother to baby. Identify which option involves a medical intervention to stimulate the immune system.

Conclude that vaccination is the correct answer as it is a deliberate introduction of antigens to develop immunity, fitting the definition of active artificially acquired immunity.

Open Question

Your friend tests her snake-wrangling skills on an eastern diamondback rattlesnake, and is bitten and envenomated (injected with the snake's venom). In the emergency department, doctors administer the antivenin CroFab, which contains antibodies to the toxins in snake venom. Is this an example of active or passive immunity? Will this confer any lasting protection to your friend?
