Detailed explanation-1: -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. Only active immunity is long-lasting.

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: -A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one’s own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body.

Detailed explanation-4: -The greatest downside to passive immunity is that these antibodies don’t stay in the body for very long. Because your body isn’t continually reacting to specific pathogens, the antibodies that fight them will die off without restocking.
