    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, hepatitis B, influenza, measles mumps, rubella, polio, rotavirus and varicella. Fever is associated with febrile seizures in infants. Thus, many vaccines prevent fever and febrile seizures by protecting against natural…

    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 currently routinely recommended to the general population in the U.S.* have not been shown to cause ataxia. Epidemiological Evidence The 2012 report by the Institute of Medicine (IOM), now called…

    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 allergy to a vaccine component. Also, vaccines can cause large local swelling reactions or nodules at the injection site due to delayed-type hypersensitivity reactions. International consensus for evaluation…

    Conclusion Myocarditis can be induced by either viral or bacterial infection, most notably developing in up to two thirds of persons infected with diphtheria. Thus, diphtheria vaccine prevents myocarditis by protecting against natural infection. Smallpox vaccine can very rarely cause myocarditis and myocardiopathy/cardiomyopathy, but is not routinely recommended to the general population in the United…

    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 2012 report by the Institute of Medicine (IOM) 1, now called the National Academy of Medicine (NAM), described two studies assessing optic neuritis and MMR, influenza, hepatitis B,…

    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 Evidence Most studies described in the 2012 report by the Institute of Medicine (IOM), now called the National Academy of Medicine (NAM), found no association between vaccination…

  • Do Vaccines Cause Facial Nerve Palsy?

    by

    in

    Conclusion Natural infections with varicella, tetanus and diphtheria have each been associated with facial nerve palsy. Thus, varicella, tetanus and diphtheria vaccines prevent facial nerve palsy by protecting against these natural infections. Vaccines currently routinely recommended to the general population in the U.S.* have not been shown to cause facial nerve palsy. Epidemiological Evidence 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 The 2012 report by the Institute of Medicine (IOM), now called the National Academy of Medicine (NAM), found no relevant studies of quality in the literature assessing CIDP and MMR,…

  • Do Vaccines Cause Arthralgia or Arthritis?

    by

    Tina
    in

    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 cause mild, acute, transient arthralgia or arthritis, rarely in children but commonly in certain adult women (between 10-25% of adult female vaccinees without preexisting rubella immunity), usually beginning 1-3…
