-The preferred intramuscular site is the deltoid muscle of the upper arm.
-The preferred intradermal site is the deltoid; having the patient place the hand of the arm being immunized on their hip so that it bends at the elbow creates a more accessible angle.
-Inspect for particulate matter and/or discoloration.
-Use separate syringes for each injection.

-Refrigerate; do not freeze
-Discard if product has been frozen
