An example of naturally occurring passive immunity is the transfer of antibodies from a mother to her baby during pregnancy and breastfeeding. During pregnancy, antibodies are passed through the placenta, providing the newborn with immediate protection against infections. Additionally, breast milk, particularly colostrum, contains antibodies that further support the infant's immune system after birth. This type of immunity is temporary, as the transferred antibodies will eventually decline over time.
A source of passive immunity is when antibodies are transferred from one individual to another. This can occur naturally through breastfeeding or transplacentally from mother to fetus, or artificially through administration of pre-formed antibodies, such as in immune globulin injections.
Passive immunity happens when the antibody is already given to you. For example, the antibody that can be passed from mother to child. That is a natural passive immunity. The vaccine given to you when had rabies is also an example of passive immunity because again, what is given to you is already an antibody.
Passive immunity because the antibodies pass from mother to fetus.

Passive Immunity & Acquired Immunity ,
Active immunity is long term protection that generally lasts 20-30 years and passive immunity is immediate protection. there are two forms, naturally acquired and artificially acquired. in active immunity the naturally acquired immunity is when you suffer from the disease then recover again. the artificially acquired way is by getting a vaccination. in passive immunity, the naturally acquired way is to receive antibodies from mother in pregnancy and breastfeeding, the artificial way is to have antibodies injected in a serum for immediate response for example when you have been bitten by a poisonous animal. note they are not vaccinated.
Memory cells are not produced in passive immunity because passive immunity involves the transfer of pre-formed antibodies, either naturally (e.g., from mother to fetus) or artificially (e.g., through administration of antibodies). Since memory cells are generated through exposure to antigens, which triggers an immune response and the formation of memory cells, passive immunity does not involve this process.
passive acquired
Receiving antivenom after a snake bite would be an example of passive immunity, where antibodies are transferred from another source (in this case, the antivenom) to provide immediate protection against the venom.
Passive immunity can be given naturaly or artificially.Natural Passive Immunity can be acquired from the maternal colustrum and maternal placenta.While artificial passive immunity is given parenteraly examples are: anti tetanus serum and antivenin.
