In which type of immunity do antibodies come from another person or animal?

The type of immunity where antibodies come from another person or animal is known as artificial passive immunity. This form of immunity occurs when antibodies are administered to an individual, providing temporary protection against specific pathogens. Unlike other forms of immunity, which rely on the individual's immune system to produce antibodies either naturally or through vaccination, artificial passive immunity involves the transfer of pre-formed antibodies to the recipient. This is typically achieved through the use of serum or immunoglobulin derived from donors who have already developed immunity, such as those who have recovered from an infection or have been immunized against a disease.

This method is particularly useful in situations where immediate immunity is required, such as in cases of exposure to certain toxins or infections where the body may not have time to respond by producing its own antibodies. This contrasts with natural passive immunity, where antibodies are transferred from mother to child through the placenta or breast milk, and artificial active immunity, where a vaccine stimulates the body to produce its own antibodies. Therefore, artificial passive immunity is the precise term that captures the process of receiving antibodies originated in another individual or animal for immediate, albeit temporary, protection.
