Questions & Step-by-Step Solutions
A child receives a measles vaccine. What type of immunity is conferred by this vaccination?
Correct Answer: Active immunity
Step 1: Understand that a vaccine is a substance that helps protect against diseases.
Step 2: Know that the measles vaccine contains a weakened or inactive form of the measles virus.
Step 3: When the child receives the vaccine, their immune system recognizes the weakened virus as a threat.
Step 4: The immune system responds by producing antibodies, which are proteins that fight off infections.
Step 5: This process of the immune system creating its own antibodies is called active immunity.
Step 6: As a result, the child becomes immune to measles, meaning they are less likely to get sick from it in the future.
Active Immunity – Immunity that develops as a result of exposure to a pathogen or through vaccination, leading to the production of antibodies by the immune system.
