Appropriate medical treatment & supervision should be readily available in case of anaphylactic event following vaccination. Do not administer intravascularly. Individuals w/ thrombocytopenia or any coagulation disorder since bleeding may occur following an IM administration. Anxiety-related reactions including vasovagal reactions (syncope), hyperventilation or stress-related reactions can occur following, or even prior to vaccination; can be accompanied by several neurological signs (eg, transient visual disturbance, paresthesia & tonic-clonic limb movements during recovery). Have procedures in place to avoid injury from faints. Not effective against all possible influenza virus strains. Intended to provide protection against virus strains from which the vaccine is prepared & to closely related strains. Protective immune response may not be elicited in all vaccinees. Patients w/ endogenous or iatrogenic immunosuppression. Interference w/ serological testing. Contains Na 23 mg/dose & K 39 mg/dose. Infants <6 mth.
