Active artificial immunity arises from:

Explanation:
Active immunity is when the body’s own immune system responds to an antigen by making antibodies and memory cells. Vaccination provides a controlled exposure to an antigen, prompting the immune system to respond and establish memory without causing disease—this is active artificial immunity. In contrast, infection would cause active immunity naturally, while serum injections deliver preformed antibodies, giving passive immunity, and maternal antibodies are also passive.
