Passive immunity is temporary because it involves the transfer of pre-formed antibodies from an external source, such as through breast milk or intravenous immunoglobulin. Since the recipient's immune system is not actively producing these antibodies, the protection provided is short-term and wanes as the transferred antibodies are broken down and eliminated from the body.
is temporary and does not involve the individual’s immune system producing antibodies. Instead, passive immunity provides ready-made antibodies obtained from another source, such as through injection of antibodies or transfer of antibodies from mother to fetus.
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.
Active immunity requires exposure to the antigen, either naturally or artificially, in order for the immune system to build antibodies against it. Passive immunity does not require exposure to the antigen because the antibodies are obtained either naturally, through mother's milk, or artificially through an injection of a serum, such as that is used in antivenom for snake bites.
transfer of antibodies from a mother to her baby through the placenta or breast milk. This provides temporary protection to the baby against certain diseases as the baby's immune system is still developing.
specificity the quality of having a certain action, as of affecting only certain organisms or tissues, or reacting only with certain substances, as antibodies with certain antigens (antigen specificity).
The four types of immunity are innate immunity, adaptive immunity, passive immunity, and active immunity. Innate immunity is the body's first line of defense, providing immediate but non-specific protection against pathogens. Adaptive immunity develops over time and involves a specific response to pathogens, including the production of antibodies. Passive immunity involves the transfer of antibodies from one individual to another, such as from mother to child, while active immunity refers to the immune system's response to a vaccine or infection, leading to long-lasting immunity.
Passive immunity is the transfer of active humoral immunity in the form of readymade antibodies, from one individual to another. Passiveimmunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and can also be induced artificially, when high levels of human (or horse) antibodies specific for a pathogen or toxin are transferred to non-immune individuals. Passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases.
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.

Both active and passive immunity provide protection against infections and diseases by enabling the body to recognize and respond to pathogens. They involve the immune system's production of antibodies, although active immunity results from the body's own immune response to an infection or vaccination, while passive immunity involves the transfer of antibodies from another source, such as maternal antibodies or intravenous immunoglobulin. Additionally, both types can help prevent illness and can be crucial in providing immediate or long-term protection.
Active immunity requires exposure to the antigen, either naturally or artificially, in order for the immune system to build antibodies against it. Passive immunity does not require exposure to the antigen because the antibodies are obtained either naturally, through mother's milk, or artificially through an injection of a serum, such as that is used in antivenom for snake bites.
A mother may transfer some IgG antibodies passively through the placenta to the fetus.
Active immunity occurs when the body produces its own antibodies in response to an infection or vaccination, providing long-term protection. In contrast, passive immunity involves the transfer of antibodies from another source, such as from mother to baby through breast milk or through antibody treatments, offering temporary protection. While active immunity develops over time and can last for years, passive immunity is immediate but short-lived, typically lasting only a few weeks to months.
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.
