What is the mechanism of action of the vaccine for measles, mumps, and rubella (MMR)?

Step 1: The MMR vaccine contains weakened (attenuated) forms of the measles, mumps, and rubella viruses.
Step 2: When the vaccine is injected into the body, the immune system recognizes these weakened viruses as foreign invaders.
Step 3: The immune system responds by producing antibodies and activating immune cells to fight off the viruses.
Step 4: This immune response helps the body remember how to fight these viruses in the future.
Step 5: If the person is later exposed to the actual viruses, their immune system can quickly respond and prevent illness.
