1. Patient: 2-month old well female infant 

    • Site of injection:
      • Pneumococcal conjugate vaccine (PCV): right anterolateral thigh
      • Pentavalent vaccine (Penta): left anterolateral thigh
    • Target muscle: Vastus lateralis muscle
      • Origin: Greater trochanter and linea aspera of femur
      • Insertion: Patella via quadriceps tendon and then tibial tuberosity via patellar ligament 
      • Action: Extends knee
    • Locating the area: Muscle must be divided into thirds, then the injection will be administered into the middle third of the muscle, lateral to the midpoint in the outer anterolateral aspect

2. Patient: 65-year-old grandfather

    • Site of injection: Upper arm, around the shoulder
    • Target muscle: Deltoid
      • Origin: Acromial extremity of clavicle (anterior fibers), acromion of scapula (lateral fibers), and spine of scapula (posterior fibers)
      • Insertion: Deltoid tuberosity of humerus
      • Action: Lateral fibers abduct arm at shoulder joint; anterior fibers flex and medially rotate arm at shoulder joint; posterior fibers extend and laterally rotate arm at shoulder joint
    • Locating the area: Envision an inverted triangle on the patient's arm by placing two fingers down from the acromion process, administer the vaccine in the center of the inverted triangle
