The infectiousness of diseases such as: the measles, rubella, the mumps, and the chicken pox is quite strong. When people lack antibodies to these diseases, the chance for infection increases. On a university campus, a person without such antibodies can help spread such diseases. However, as vaccines are available for these diseases and people are vaccinated, the chance for infection and the spreading of these diseases will diminish. At our university, Tokyo University of Pharmacy and Life Sciences, at the start of the recent academic year, an antibody survey was taken of 2,647 students to see which students had lower levels of antibodies to help fight the spread of the aforementioned diseases. Our findings showed antibody-positive rates of 49.0% for the measles, 70.8% for rubella, 75.7% for the mumps, and 92.4% for the chicken pox. With the rate for the chicken pox being the only one meeting an acceptable standard (Fine) in terms of community immunity. On the other hand, although the vaccination rates for the measles and rubella were high, they did not meet an acceptable standard for community immunity (Fine). When the community immunity level is low, the risk of infection is increased and this could lead to an outbreak on campus and affect more than just individuals. In the future, we will encourage students to be fully vaccinated before entering school or soon after doing so in order to protect against such an outbreak from occurring.
