What is passive immunity and what is active immunity give examples of each?

Passive immunity is the short-term protection provided by antibodies that are transferred from one individual to another, such as from mother to child through breast milk or through antibody injections (e.g., anti-venom). In contrast, active immunity occurs when the immune system produces its own antibodies in response to an infection or vaccination, such as developing immunity after recovering from chickenpox or after receiving a flu vaccine.
