Factors influencing MMR vaccination decisions following a mumps outbreak on a university campus

Following a number of mumps outbreaks in universities and colleges, the UK Health Protection Agency has suggested that it is appropriate to consider offering the MMR vaccine in these settings. However, little is known about the factors associated with uptake of the MMR jab or perceptions of risks/benefits of the vaccine among higher education students. The current study focused on a sample of students offered the MMR vaccine following an outbreak of mumps on a university campus. Perceptions of risks/benefits of the vaccine varied considerably and students were unlikely to have the jab when perceived risks of immunising were equivalent to perceived risks of not immunising. Results suggest that public health interventions should address students’ attitudes towards the vaccine, perceptions of peer expectations, and perceptions of barriers to uptake.
