SITE FOR INJECTION: The preferred injection site for infants and young children is the vastus lateralis muscle in the anterolateral thigh
TARGETED MUSCLE: Vastus Lateralis
ORIGIN: It originates from the upper intertrochanteric line of the femur.
INSERTION: Lateral quadriceps tendon which is attached over the tibial tubercle.
ACTION: Lower leg extension and allows the body to rise rise from sitting
HOW TO LOCATE AREA: Position the patient into supine position. Palpate the thighs and locate the area between the greater trochanter and the lateral femoral condyle. Divide the region into three areas and administer the vaccine in the middle part of the divided part.
