Administration advice:

• Administer IM; the preferred site is the anterolateral aspect of the thigh in patients under 1 year, and the deltoid muscle for older children and adults.
• Do not administer in the gluteal region: response may be suboptimal.
• Administer subcutaneously only in patients at risk of hemorrhage from IM injections.

• Shake well before use to form a homogenous, turbid white suspension.

• Do not mix with any other vaccine or product in the same syringe/vial.

• Health care providers should report any allergic or unusual adverse reactions to the Vaccine Adverse Event Reporting System (VAERS) at 1-800-822-7967 (USA) and the manufacturer.
