Warnings
Contraindications
Hypersensitivity to eggs, sulfites (persons with hives-only allergy to eggs, can receive the inactivated influenza vaccine)
Cautions
Use split or purified surface antigen in children
Defer vaccine with febrile illnesses until illness is resolved; may administer vaccine with minor illnesses without fever (eg, URIs)
Expected immune response may not be obtained in immunocompromised individuals, including those receiving immunosuppressive therapy
Syncope (fainting) can occur in association with administration of injectable vaccines; can be accompanied by transient neurological signs such as visual disturbance, paresthesia, and tonic-clonic limb movements; procedures should be in place to avoid falling injury and to restore cerebral perfusion following syncope by maintaining a supine or Trendelenburg position
Vaccination may not protect all vaccine recipients against influenza disease
Pregnancy & Lactation
Pregnancy Category: B/C (manufacturer specific)
CDC recommends Influenza vaccine be administered during pregnancy (all trimesters); vaccination during pregnancy shown to decrease risk of illness in the mother, as well as the risk of influenza and influenza hospitalization in their infants during the first 6 months of life (MMWR August 26, 2011;60[33]:1128-32)
Lactation: excretion in milk unknown; use with caution
Pregnancy Categories
A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA:Information not available.
Pharmacology
Mechanism of Action
Inactivated influenza virus types A & B subunits
Convey active immunity via stimulation of production of endogenously produced antibodies
Pharmacokinetics
