Passive immunity is acquired from an external source, such as through receiving antibodies from another individual or through antibody-containing products like vaccines or immunoglobulin injections. This type of immunity provides immediate protection but is temporary because the body does not produce its own memory cells. Passive immunity is used in situations where immediate protection is needed, such as in cases of exposure to a virus or toxin.
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 acquired from maternal antibodies during pregnancy or breastfeeding generally only lasts for 3-6 weeks.
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 immunity is the transfer of ready-made antibodies from one individual to another. This can occur naturally, such as when a baby receives antibodies from its mother through breast milk, or artificially, through the administration of antibodies derived from another individual or animal to provide protection against a specific pathogen. The immunity provided by passive transfer is temporary and does not result in long-lasting protection.
Passive immunity involves the bodies defenses which do not change for different types of microbes. This would be like Natural Killer B cells which attack a wide variety of microbes. Active immunity involves your body becoming acclimated toward a bacteria or virus, such that future contact will spur on a triggered response. An example of this would be the production of antibodies.
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.
Passive immunity because the antibodies pass from mother to fetus.

active immunity is the immunity that is stimulated internally as a a result of antibodies entering the body. Passive is stimulated by substances from an external source
The three types of immunity is innate immunity, adaptive immunity, and passive immunity.
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.

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.
Natural passive immunity can be reached through the passing of mother's antibodies through the placenta or through milk during breastfeeding. These types of passive immunity only last for about 3 months after birth. Artificial passive immunity can be reached through intravenous injection of antibodies.
