A 9-month-old child receives Measles-Rubella (MR) vaccine as per the Indian NIS. Which of the following is the CORRECT route and site of administration?
- A Subcutaneous, right upper arm outer aspect ✓
- B Intradermal, left upper arm
- C Intramuscular, anterolateral thigh
- D Oral, any route
Correct answer: A. Subcutaneous, right upper arm outer aspect
Explanation
MR vaccine (and all live viral vaccines including MMR, Varicella) is given subcutaneously, typically in the outer aspect of the right upper arm. Intradermal route is used for BCG. Intramuscular route is used for DPT, Hepatitis B, IPV, PCV, and Rotavirus (IM formulation). The subcutaneous route achieves adequate immune response while minimizing local reactions for live attenuated vaccines.
