Conclusion | Epidemiological Evidence | Proposed Biological Mechanism | Archives | ReferencesConclusion Older formulations of rabies vaccine did cause Acute Disseminated Encephalomyelitis (ADEM), but newer formulations of rabies vaccine have not been shown to
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) can
Conclusion Natural infection with influenza can contribute to asthma exacerbation. Thus, influenza vaccine prevents asthma exacerbation by protecting against natural infection. Influenza vaccines do not
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 by the
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 Evidence The
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 persons with
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 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 cause MS. Epidemiological
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: PandemrixTM) was associated with an increased risk of narcolepsy in several northern European countries. In
Conclusion Vaccines in routine use in the United States* have not been shown to cause oculorespiratory syndrome (ORS). Vaccines in routine use in the United States* have not
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 Evidence The
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 women 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.42F* have not been shown to cause systemic lupus erythematosus (SLE). Epidemiological evidence The
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.
