Where is the MMR vaccine administered in children?

• A. Intravenously in the hand
• B. Intramuscularly in the thigh
• C. Subcutaneously in the upper arm
• D. Orally

Answer: (C)

The MMR vaccine, which protects against measles, mumps, and rubella, is administered subcutaneously in the upper arm for children. This method of administration is effective because vaccines that are given subcutaneously allow for slower absorption into the bloodstream, which can be beneficial for the immune response. The upper arm is the preferred site since it is an area that is easy to access and has sufficient fatty tissue to accommodate the subcutaneous injection. The other administration routes listed are not appropriate for the MMR vaccine. Intravenous administration is typically reserved for specific medications or treatments that need rapid effect, which is not applicable for vaccines. Intramuscular injections in the thigh are commonly used for certain vaccines, particularly in infants, but the MMR vaccine is specifically recommended for subcutaneous delivery. Oral administration is used for some vaccines, like the rotavirus vaccine, but not for the MMR vaccine, which requires a subcutaneous injection to confer immunity effectively.
