Which type of immunization does a newborn receive from the mother?

• A. Active immunity
• B. Natural passive immunity
• C. Artificial immunity
• D. Herd immunity

Answer: (B)

The correct answer, natural passive immunity, is rooted in the biological mechanisms of how a newborn acquires protective antibodies from the mother. During pregnancy, a mother transfers immunoglobulin G (IgG) antibodies to her fetus through the placenta. This process provides the newborn with immediate but temporary protection against infections, as these antibodies can help fight off pathogens that the mother has been exposed to, thus giving the infant an important layer of immunity right from birth. As the newborn continues to develop, the immunity received from the mother begins to wane, which is why vaccinations are typically administered shortly after birth to help establish the infant's own active immunity over time. Natural passive immunity is characterized by the transfer of antibodies without the infant's immune system having to produce them itself, which differentiates it from active immunity where the body would generate its own antibodies in response to a vaccine or infection. In contrast, other options describe different concepts of immunity. Active immunity arises when an individual's immune system responds to a pathogen or a vaccine, resulting in the production of its own antibodies. Artificial immunity refers specifically to immunity gained through medical intervention, such as vaccinations, rather than through natural means. Herd immunity involves a population level of immunity, where a significant portion is immunized enough to
