Conclusion Certain combination vaccines or simultaneous administration of vaccines that are known to cause fever can rarely cause febrile seizures in infants and young children
Conclusion Older formulations of rabies vaccine did cause Acute Disseminated Encephalomyelitis (ADEM), but newer formulations of rabies vaccine have not been shown to cause ADEM,
Conclusion Infections may trigger or contribute to the pathogenesis of arthritis. Thus, vaccines may prevent arthritis by protecting against natural infections. Rubella-containing vaccines (e.g. MMR)
Conclusion Natural infection with respiratory syncytial virus (RSV) in infancy can increase the risk of asthma in childhood, as well as contribute to asthma exacerbation.
Conclusion Vaccines currently routinely recommended to the general population in the U.S.* have not been shown to cause brachial neuritis. Epidemiological Evidence The 2012 report
Conclusion Vaccines currently routinely recommended to the general population in the U.S.* have not been shown to cause chronic inflammatory disseminated polyneuropathy (CIDP). Epidemiological Evidence
Conclusion Vaccines currently routinely recommended to the general population in the U.S.* have not been shown to cause fibromyalgia or chronic fatigue syndrome (CFS). Epidemiological
Conclusion Influenza vaccines reduce the risk of influenza infection, which causes Guillain-Barré syndrome (GBS). Thus, influenza vaccines prevent GBS by protecting against natural influenza infection.
Conclusion Natural infection with hepatitis viruses is known to cause hepatitis disease. Natural infection with measles, mumps, rubella and varicella viruses have also been associated
Conclusion Vaccines can very rarely cause immediate hypersensitivity reactions (i.e. anaphylaxis, angioedema, and/or hives) usually within minutes, but up to several hours of vaccination in
Conclusion Influenza vaccines do not cause multiple sclerosis (MS).Other vaccines currently routinely recommended to the general population in the U.S.* have not been shown to
Conclusion Myocardial infarction (MI) has been associated with natural influenza infection, and stroke has been associated with natural varicella infection, albeit both very rarely. Thus,
Conclusion The AS03-adjuvanted 2009 pandemic H1N1 influenza vaccine (trade name: Pandemrix™) was associated with an increased risk of narcolepsy in several northern European countries. In
Conclusion The Fluviral S/F® and Vaxigrip® vaccines used in Canada between 2000 and 2003 (but never used in the United States) did commonly cause oculorespiratory
Conclusion Vaccines currently routinely recommended to the general population in the U.S.* have not been shown to cause optic neuritis or neuromyelitis optica (NMO). Epidemiological
Conclusion Fever is a common symptom of many natural infections, including bacteria such as diphtheria, pertussis, meningococcus and pneumococcus, and viruses such as hepatitis A,
Conclusion Vaccines currently routinely recommended for pregnant individuals in the U.S. have not been shown to cause spontaneous abortion (SAb). Why This Is An Issue
Conclusion Vaccines currently routinely recommended to the general population in the U.S.* have not been shown to cause systemic lupus erythematosus (SLE). Epidemiological Evidence The
Conclusion Natural viral infections such as influenza, varicella, measles, mumps and rubella are associated with immune thrombocytopenic purpura (ITP). Thus, influenza, varicella, measles, mumps and
Conclusion Natural viral infections with influenza, hepatitis A, measles, mumps and rubella and varicella have all been associated with transverse myelitis, albeit rarely. Thus, these
Vaccines currently routinely recommended to the general population in the U.S have not been shown to cause vasculitis or PAN.
