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 beyond the
Conclusion Certain ingredients that are present in some vaccines (other than disease-specific antigens), such as gelatin or neomycin, can very rarely cause severe hypersensitivity reactions (e.g. anaphylaxis)
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, and rabies vaccine is
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 mumps and varicella infections are associated with acute cerebellar ataxia. Thus, mumps and varicella vaccines prevent ataxia by protecting against natural infection. Vaccines
Conclusion Childhood vaccines do not cause autism. Maternal vaccines have not been shown to cause autism. The Institute of Medicine (IOM), now called the National Academy of Medicine (NAM),
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 Natural infections with viruses such as measles and mumps have been associated with both transient and permanent hearing loss. Thus, measles and mumps vaccines
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 Varicella vaccines can rarely cause herpes zoster due to vaccine-strain viral reactivation. Other vaccines currently routinely recommended to the general population in the U.S.* do not cause vaccine-strain
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 Varicella vaccine in routine use in the United States can very rarely cause viral meningitis. Measles-containing vaccines can very rarely cause measles inclusion body encephalitis (MIBE). Mumps vaccines
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 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 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.
