Seroprevalence of anti-mumps virus IgG antibody titer and voluntary mumps vaccination coverage in young adults in Japan

In Japan, monovalent vaccine against mumps virus (MuV) infection was shifted to a voluntary basis vaccination due to the incidences of aseptic meningitis in the past. According to an analysis of a total of 409 participants aged 18–20 years, overall vaccination coverage rate was 48%. The mean anti-Mu...

Description
Summary:In Japan, monovalent vaccine against mumps virus (MuV) infection was shifted to a voluntary basis vaccination due to the incidences of aseptic meningitis in the past. According to an analysis of a total of 409 participants aged 18–20 years, overall vaccination coverage rate was 48%. The mean anti-MuV IgG antibody titer of participants with medical history and more than two times vaccination was significantly higher than that in those without a medical history and unvaccinated and single vaccination, respectively. Seropositivity against MuV infection was >50% regardless of the number of vaccinations. Although these results suggest that seropositivity may persist due to asymptomatic infection, it is necessary to implement either a high vaccine coverage or routine vaccination for prevention of periodic mumps epidemics.
