    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 with hepatitis, albeit rarely. Thus, measles, mumps, rubella and varicella vaccines, and especially hepatitis A and hepatitis B vaccines, prevent hepatitis disease by protecting against natural infection. Vaccines currently routinely…

    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 Vaccines currently routinely recommended to the general population in the U.S.* have not been shown to cause complex regional pain syndrome (CRPS). 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 CRPS and vaccination1.…

    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…
