While Hernan came to same results for immunization against influenza or tetanus in a case-control study (evidence class II), active immunization against hepatitis B was reported to pose a higher risk for MS (50) . A case-control study on vaccination against hepatitis B, influenza, polio, diphtheria, pertussis, tetanus, measles, mumps, rubella, Japanese encephalitis, meningitis, hepatitis A, varicella and rabies did not reveal an increased risk for the onset of ADEM in the time spans of 0-30 days and 61-180 days after vaccination, but between 31 and 60 days (78) .	./cache/cord-003828-bhfghcby.txt	./txt/cord-003828-bhfghcby.txt
