- Administer vaccine to children in deltoid muscle with adequate deltoid muscle mass needles ⅞ to 1¼ inches in length to ensure penetration of muscle mass.
- Administer vaccine to infants older than 6 mo of age and young children in anterolateral aspect of thigh using needles ⅞ to 1 inch in length to ensure penetration of muscle mass.
- If influenza A (H1N1) 2009 injection vaccine is to be given at the same time as another injectable vaccine(s), the vaccine(s) should always be administered at different injection sites

Store in refrigerator at 36° to 46°F; do not freeze.
Do not administer intranasal influenza A (H1N1) vaccine until 48 h after cessation of antiviral therapy; do not administer antivirals until 14 days after giving intranasal influenza A (H1N1) vaccine unless medically indicated.Aspirin
Because of the association of Reye syndrome with aspirin and wild-type influenza infection, intranasal influenza A (H1N1) vaccine is contraindicated in children and adolescents receiving aspirin or aspirin-containing products.Hydantoins (eg, phenytoin), theophylline, warfarin
Clearance of these agents may be inhibited by influenza vaccine; however, no adverse clinical effects have been reported.Immunosuppressive agents (eg, corticosteroid)
The response to influenza A (H1N1) vaccine may be diminished.Vaccines
There are no data to assess concurrent use of other vaccines with influenza A (H1N1) vaccine.

Influenza A (H1N1) vaccination may not protect all persons.
Defer vaccination in patients with acute febrile illness for at least 72 h or until symptoms have abated.
Avoid administration to persons known to have experienced Guillain-Barré syndrome within 6 wk after a previous influenza vaccination unless benefit outweighs the risk.
Intranasal influenza A (H1N1) vaccine is not indicated for persons with underlying medical conditions that could predispose them to severe disease following wild-type influenza infection (eg, patients with chronic disorders of the CV and pulmonary systems, pregnant women, chronic metabolic diseases requiring regular medical follow-up or hospitalization during the proceeding year, renal function impairment, hemoglobinopathies).
Immune response may be diminished. Because intranasal influenza A (H1N1) vaccine is a live virus vaccine, use with caution in immunocompromised persons.
- Review benefits and risks of the vaccine and importance of completing the immunization series.
- Provide patient, parent, or guardian with immunization history record and record this immunization in patient immunization record.
- Provide and review patient information leaflet prior to immunization.
- Advise patient, parent, or caregiver that vaccine will be prepared and administered by health care provider.
