Side Effects by Body System - for Healthcare Professionals
Applies to: nasal spray
Respiratory side effects have frequently included cough, runny nose, and nasal congestion. Otitis media, sneezing, rhinitis, sinusitis, and epistaxis have also been reported.
In a clinical trial, among children 6 to 23 months of age, wheezing requiring bronchodilator therapy or with significant respiratory symptoms occurred in 5.9% of FluMist recipients compared to 3.8% of active control (injectable influenza vaccine made by Sanofi Pasteur Inc) recipients (Relative Risk 1.5, 95% CI: 1.2, 2.1). Wheezing was not increased in children 24 months of age and older.
Gastrointestinal side effects have frequently included sore throat and vomiting. Abdominal pain and diarrhea have been infrequently reported. Nausea has been reported rarely.
Musculoskeletal side effects have frequently included muscle aches.
Other side effects have included decreased appetite, irritability, decreased activity, tiredness/weakness, headache, muscle aches, chills, and fever.
Nervous system side effects have included Guillain-BarrÃ© syndrome, Bell's Palsy, meningitis, eosinophilic meningitis, and vaccine-associated encephalitis. The frequency and/or causal relationship has not been established.
An increased frequency of Guillain-Barre syndrome (GBS) was reported in 1976 with the administration of the swine influenza vaccine. Among individuals who received the swine influenza vaccine in 1976, the rate of GBS that exceeded the background rate was <10 cases per 1 million persons vaccinated with the risk for influenza vaccine-associated GBS higher among individuals over 25-years-old compared to individuals younger than 25-years-old. GBS has an annual incidence of 10 to 20 cases per 1 million adults; therefore it is difficult to obtain strong epidemiologic evidence for a possible increase in risk. Investigations, to date, have not reported a substantial increase in the incidence of GBS associated with influenza vaccines (other than the 1976 swine influenza vaccine), and if influenza does pose a risk, it is probably slightly more than 1 additional case per 1 million individuals vaccinated.
Dermatologic side effects have included rash.
Hypersensitivity reactions have included anaphylaxis, facial edema, and urticaria.
Cardiovascular side effects in post-marketing reports have included pericarditis. The frequency and relationship to vaccine exposure has not been determined.Top
