What is the minimum age for receiving the MMR (Measles, Mumps, Rubella) vaccine?

• A. 6 months
• B. 12 months
• C. 18 months
• D. 2 years

Answer: (B)

The minimum age for receiving the MMR (Measles, Mumps, Rubella) vaccine is indeed 12 months. This timing is critical because the vaccine is designed to stimulate an immune response that provides effective protection against these diseases. Administering the vaccine at 12 months ensures that the child's immune system is sufficiently developed to respond to the vaccine and generate an adequate immune response. Before 12 months, infants typically have maternal antibodies that can interfere with the effectiveness of the vaccine. These antibodies may diminish the immune response to the vaccine, which is why it is recommended to wait until the child is at least 12 months old to ensure optimal effectiveness. Vaccination before this age may not provide the desired protection against measles, mumps, and rubella. All other age options listed—6 months, 18 months, and 2 years—are either too early or do not align with the recommended vaccination schedule. The 18-month mark is often when the first booster is given, and the 2-year mark is too late for the initial dose, as the vaccine is typically provided around one year of age.
