Summarize this article in one sentence.
Wash your hands thoroughly with warm water and soap. Lather the soap for at least 30 seconds and scrub under your nails, between your fingers, and up your wrists. Dry your hands with a clean paper towel.  You can also put on disposable gloves to administer the injection. Make sure your patient doesn’t have a latex allergy; if so, use non-latex gloves such as those made out of nitrile. MMR is delivered subcutaneously, into the fatty tissue beneath the skin and above the muscle layer. For patients under 12 months old, choose a fatty site over the upper outer (anterolateral) thigh muscle. For anyone over 12 months, you can use the anterolateral thigh or the fatty tissue over the triceps muscle. Ask adult patients if they prefer one injection site over another. Open a new, sterile alcohol wipe. Rub the site in a circular motion starting in the center and extending out 2-3 inches. Let the alcohol dry. If giving more than one vaccine, use a separate injection site for each one. You can give MMR on the same day as other vaccines. Stabilize the arm or leg that will receive the injection with your non-dominant hand. Gently pinch up the skin to allow for better access to the fatty layer. Hold the needle about an inch from your patient. Quickly insert the needle at a 45° angle to the patient’s body. Push down on the plunger with steady pressure to inject the vaccine.   Remove the needle at the same angle you inserted it. Dispose of the needle in a sharps container. Do not attempt to recap the needle unless it has a built-in safety cap device. Apply gentle pressure to the area immediately after removing the needle. Cover this with a small piece of gauze and hold it in place with medical tape. Inform your patient they can remove the bandage later that day.

Summary:
Wash your hands. Select the injection site. Clean the injection site with an alcohol wipe. Give the shot at a 45° angle to the patient’s body. Wipe and bandage the area.
