Adverse Reactions to Fluvirin Flu Shot

Adverse Reactions to Fluvirin Flu Shot

  • Body as a whole: Local injection site reactions (including pain, pain limiting limb movement, redness, swelling, warmth, ecchymosis, induration), hot flashes/flushes; chills; fever; malaise; shivering; fatigue; asthenia; facial edema.
  • Immune system disorders: Hypersensitivity reactions (including throat and/or mouth edema). In rare cases, hypersensitivity reactions have lead to anaphylactic shock and death.
  • Cardiovascular disorders: Vasculitis (in rare cases with transient renal involvement), syncope shortly after vaccination.
  • Digestive disorders: Diarrhea; nausea; vomiting; abdominal pain.
  • Blood and lymphatic disorders: Local lymphadenopathy; transient thrombocytopenia.
  • Metabolic and nutritional disorders: Loss of appetite.
  • Musculoskeletal: Arthralgia; myalgia; myasthenia.
  • Nervous system disorders: Headache; dizziness; neuralgia; paraesthesia; confusion; febrile convulsions; Guillain-BarrĂ© Syndrome; myelitis (including encephalomyelitis and transverse myelitis); neuropathy (including neuritis); paralysis (including Bell’s Palsy).
  • Respiratory disorders: Dyspnea; chest pain; cough; pharyngitis; rhinitis.
  • Skin and appendages: Stevens-Johnson syndrome; sweating; pruritus; urticaria; rash (including non-specific, maculopapular, and vesiculobulbous).
Other Adverse Reactions associated with Influenza Vaccination Anaphylaxis has been reported after administration of FLUVIRIN®. Although FLUVIRIN® contains only a limited quantity of egg protein, this protein can induce immediate hypersensitivity reactions among persons who have severe egg allergy. Allergic reactions include hives, angioedema, allergic asthma, and systemic anaphylaxis.

The 1976 swine influenza vaccine was associated with an increased frequency of Guillain-Barré syndrome (GBS). Evidence for a causal relation of GBS with subsequent vaccines prepared from other influenza viruses is unclear. If influenza vaccine does pose a risk, it is probably slightly more than 1 additional case/1 million persons vaccinated.

Neurological disorders temporally associated with influenza vaccination such as encephalopathy, optic neuritis/neuropathy, partial facial paralysis, and brachial plexus neuropathy have been reported.

Microscopic polyangiitis (vasculitis) has been reported temporally associated with
influenza vaccination.
