Passive humoral immunity, while providing immediate protection against pathogens through the transfer of antibodies, has several drawbacks. It offers only temporary immunity, as the transferred antibodies degrade over time and do not stimulate the recipient's immune system to produce its own antibodies. Additionally, it does not provide long-lasting memory against pathogens, leaving individuals vulnerable to reinfection. Lastly, there is a risk of allergic reactions or other adverse effects from the foreign 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.
humoral immunity
Actually acquired immunity consists of "humoral immunity" and "cell mediated immunity. Acquired immunity is the same with adaptive immunity, it is when the antibodies are produced within the bodies after the exposure of pathogen. Humoral immunity secreted antibodies while cell mediated immunity involves in production of T lymphocytes.

humoral immunity
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

humoral immunity
Humoral immunity primarily produces antibodies, which are proteins secreted by B cells in response to antigens. These antibodies circulate in the bloodstream and bind to specific pathogens, neutralizing them or marking them for destruction by other immune cells. Additionally, humoral immunity also involves the production of memory B cells, which provide long-term immunity by remembering past infections.
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.
