Measles, mumps, and rubella (MMR) are viral infections that can have serious health impacts. Measles can lead to respiratory complications and encephalitis, mumps can cause swelling of the salivary glands and potential complications like orchitis, and rubella can result in congenital defects if contracted during pregnancy. The MMR vaccine helps prevent these diseases by stimulating the immune system to produce a response without causing the illnesses, thereby protecting the body from potential serious health issues associated with these viruses.
