Placental transfer of antibodies
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.
D. Active natural immunity. Breastfeeding provides infants with natural antibodies from the mother's milk, which helps to protect the baby through active immunity.
The mother's breast milk provides passive natural immunity to the baby. This means that the baby receives antibodies from the mother through the breast milk, offering temporary immunity protection until the baby's immune system is more developed.
A form of acquired immunity resulting from antibodies that are transmitted naturally through the placenta to a fetus or through the colostrum to an infant or artificially by injection of antiserum for treatment or prophylaxis. Passive immunity is not permanent and does not last as long as active immunity.
Acquired immunity is developed by the body after exposure to a pathogen or vaccine, leading to the production of antibodies. Passive immunity is temporary protection acquired through the transfer of pre-formed antibodies, such as from mother to child during pregnancy or through receiving injections of antibodies.
Passive immunity because the antibodies pass from mother to fetus.

Passive Immunity & Acquired Immunity ,
There is innate immunity (that you are born with) and acquired immunity. Acquired immunity you get when you are vaccinated or you get the disease and fight it off. The best example is that of what we call common colds. There are about 100 different viruses that cause them. This is one reason that babies and young children seem to be always be coming down with one or getting over one.
Naturally-acquired passive immunity occurs when a fetus receives antibodies from its mother through the placenta. It also occurs when a baby receives antibodies through breastmilk.
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.
D. Active natural immunity. Breastfeeding provides infants with natural antibodies from the mother's milk, which helps to protect the baby through active immunity.
The mother's breast milk provides passive natural immunity to the baby. This means that the baby receives antibodies from the mother through the breast milk, offering temporary immunity protection until the baby's immune system is more developed.
Artificially acquired Active- vaccines (active or live viruses that are lifelong immunity) Artificially acquired Passive - gamma globulin injection that is temporary (used for overseas trips)
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.
