Detailed explanation-1: -Passive immunity: Passive immunity is “borrowed” from another source and it lasts for a short time. For example, antibodies in a mother’s breast milk give a baby temporary immunity to diseases the mother has been exposed to.

Detailed explanation-2: -The major advantage to passive immunity is that protection is immediate, whereas active immunity takes time (usually several weeks) to develop. However, passive immunity lasts only for a few weeks or months.

Detailed explanation-3: -Passive immunity – it is derived from borrowed antibodies from an animal or another person resulting in short-term immunity rather than the body producing its own.

Detailed explanation-4: -Lymphocyte A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins.

Detailed explanation-5: -For example, passive immunity occurs when a baby receives a mother’s antibodies through the placenta or breast milk. It can also occur when a person receives an injection of antibodies to protect against the effects of a toxin such as snake venom.
