Other Comments

Administration advice:

  • 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
