As a child, you received an MMR immunization against measles, mumps, and rubella. What kind of immunity do you have?

Receiving an MMR immunization against measles, mumps, and rubella results in artificial active immunity. This type of immunity is developed when an individual is exposed to a vaccine that contains antigens, which are components of pathogens. By introducing these antigens into the body, the immune system is stimulated to produce its own antibodies, allowing for a long-term immune response without the individual suffering from the actual diseases.

Artificial active immunity specifically refers to the immunity gained through vaccination, as opposed to natural exposure to the pathogens. In this case, the MMR vaccine prompts the immune system to recognize and remember the specific antigens associated with measles, mumps, and rubella, thus preparing it to fight off those infections should they occur in the future.

Natural immunity, whether passive or active, would involve gaining immunity without medical intervention, such as through recovering from an actual infection or receiving antibodies through maternal transfer. Artificial passive immunity involves the introduction of antibodies from an external source, such as through an injection, rather than having the body create its own, which does not apply in this situation.
