  1. An Evaluation of the Rubini, Urabe AM9, and Jeryl-Lynn Mumps Vaccines, Specifically Concerning Efficacy and Association with Aseptic Meningitis


    “The Urabe strain, on the other hand, has been widely confirmed as a causative agent of post-vaccine AM. The VSD project analysis, for one, has indicated risk of hospitalization for aseptic meningitis after MMR vaccination containing the Urabe strain to be 1 per 3800 doses. Despite the high efficacy of the strain in preventing mumps disease, reasons such as this have led to the end of use of the vaccine in many countries. For instance, “use of the MMR vaccine containing the Urabe mumps strain was discontinued in the UK in September 1992 following the identification of an unacceptably high risk of aseptic meningitis 15-35 days after vaccination.” Also, this same vaccine was removed from the Canadian market in 1987 due to the association between the Urabe mumps strain and aseptic meningitis. Here the risk of AM was calculated to be about 1 in 10,000 doses. However, according to a French study conducted from 1991-1993, where the associated risk was found to be 1 in 28,400 doses, the frequency of meningitis due to wild virus is still much higher at 1-3 cases per 1000 mumps cases. Thus, it can be argued that the benefit outweighs the apparently variable risk of vaccination.

    Many research efforts have been concentrated on finding out the possible cause for this high correlation of AM with the Urabe strain of the mumps vaccine. A few of these studies have led to the suggestion of genetic factors as a possible cause. In a study done in Japan by Saito et al, mumps virus isolated from nonvaccine-associated AM cases were shown to lack the BamHI restriction cleavage sites of the P gene, a phenomenon also seen in the Urabe strain. The incidence of AM in those infected with this “Urabe-like” wild-type strain, termed the ODATE-1 strain, was shown to be 70%. This observation therefore indicates a possible genetic factor, specifically concerning the P gene, playing into the incidence of aseptic meningitis among those vaccinated with the Urabe strain of mumps virus.”
