Immunity gained through mother's milk or the administration of an immune serum is described as passive immunity. This type of immunity occurs when antibodies are transferred from one individual to another, providing immediate but temporary protection against specific pathogens. In the case of mother's milk, antibodies like immunoglobulin A (IgA) are passed to the infant, while immune serum contains pre-formed antibodies that can help fight infections.
Mothers pass on immunity to diseases through their breast milk. So it is best if a mother can breast feed.
D. Active natural immunity. Breastfeeding provides infants with natural antibodies from the mother's milk, which helps to protect the baby through active immunity.
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.
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.
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.
Artificially acquired active immunity.
Theoretically it is possible to get antibodies from the serum of recovered patient of H1N1. But it will be available in very less quantity. Second question is to whom you will give these antibodies. Thirdly the protection will not be lasting. As this is passive immunity.
Passive immunity
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.
Passive humoral immunity is the transfer of pre-formed antibodies from one individual to another. This can occur naturally, such as when a newborn receives antibodies from their mother through breastfeeding, or artificially through the administration of antibody-containing products like immunoglobulin injections. Passive immunity provides immediate protection but is temporary because the transferred antibodies eventually degrade in the recipient's body.
You can get passive immunity through a placenta when you are a fetus in your mothers womb or you can be injected with antibodies that have most likely been forced to grow due to somebody putting a disease in an animal such as a rabbit. Unfortunately passive immunity does not last very long because the antibodies are detached from their white blood cells which keeps them a live and also stores the antibodies in their memory so you can not become immune forever via passive immunity as it is only passive e.g. short lived/quick
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.
