1) It is immunization day at the health center. The first patient is a 2-month-old well female infant who is scheduled for the following vaccinations: pneumococcal conjugate vaccine (PCV), pentavalent vaccine (Penta) and oral polio vaccine. PCV and Penta are given via intramuscular route. Where are the sites of injection? What muscle is targeted in the injection? Write down its origin, insertion and action. How do you locate this area?

The sites of injection are the deltoid, vastus lateralis, and ventrogluteal muscle. For patients that are under 2 years of age, the targeted site for intramuscular injection is in the vastus lateralis muscle. This muscle is used for immunizations in infants and toddlers because it is thick and well-developed. The origins of this muscle are the greater trochanter and linea aspera of the femur, its insertions are in the patella via the quadriceps tendon and then tibial tuberosity via the patellar ligament, and its action extends the leg at the knee joint. To locate the vastus lateralis, place one hand across the top thigh and the other just above the knee. The injection should be administered in between. Another way to locate it is when a toddler stands and their hands are relaxed and hanging down to their side, their middle finger dangles just over the vastus lateralis.

2) The baby’s 65-year-old grandfather also came to the center because influenza vaccine is being offered to senior citizens. The flu vaccine is given intramuscularly. Which muscle is the preferred site for IM injection in this case? Write down its origin, insertion and action. How do you locate this area?

For adults, the preferred intramuscular injection site is the deltoid muscle. The origins of this muscle are the acromial extremity of the clavicle, acromion of the scapula, and spine of the scapula, its insertions are in the deltoid tuberosity of the humerus, and its action abducts the arm, medially rotates the arm, and extend and laterally rotate the arm at the shoulder joint. To locate this area, find the acromion process to mark the base of the upside triangle. The tip of the triangle is directly below the middle of the base at about the level of the armpit. The vaccine should be administered in the middle of the triangle, about three-finger widths below the acromion process.
