Answer:
Passive
Explanation:
In addition to innate immunity and acquired immunity, there is a different type of immunity called passive immunity.
This arises when someone receives the antibodies from someone else for the purpose of preventing (or facing) an infectious disease.
While these antibodies last a few weeks or months, they have the benefit of providing immediate protection.
Examples of passive immunity:
- They are the maternal antibodies that babies receive through the placenta during pregnancy.
- Injection of antisera, produced in animals or other people, such as serum immuniglobulin for hepatitis and tetanus antitoxin.
