Florida Biology EOC Practice Test

Active immunity is the production of antibodies in response to exposure to a pathogen or vaccine. This type of immunity involves the activation of memory cells, allowing for a faster and more effective response to future infections. Option A is incorrect because active immunity can also be acquired through exposure to a weakened or dead pathogen in a vaccine. Option C is incorrect because active immunity provides long-term protection. Option D is incorrect because the immune system is directly involved in the process of active immunity.
