Detailed explanation-1: -Passive Immunity. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system. A newborn baby acquires passive immunity from its mother through the placenta.

Detailed explanation-2: -Passive immunity provides short-term protection against infection. Antibodies are proteins that bind to and help attack pathogens, such as bacteria and viruses. They are a key component of the human immune system. Typically, antibodies are produced by white blood cells in response to infection.

Detailed explanation-3: -Both natural and artificial sources of immunity can be active or passive. Natural sources aren’t specifically given to you to boost your immunity. Instead, they’re something you acquire by natural means, like an infection or from your mother during birth.

Detailed explanation-4: -Passive immunity refers to the process of providing IgG antibodies to protect against infection; it gives immediate, but short-lived protection-several weeks to 3 or 4 months at most.

Detailed explanation-5: -Active Immunity-antibodies that develop in a person’s own immune system after the body is exposed to an antigen through a disease or when you get an immunization (i.e. a flu shot). This type of immunity lasts for a long time.
