The number of reported cases of mumps in the United States has decreased steadily since the introduction of a live mumps vaccine in 1967. Although mumps is generally self-limited, meningeal signs may appear in up to 15% of cases and orchitis in up to 20% of clinical cases in postpubertal males. Other possible complications include permanent deafness and pancreatitis. Mumps vaccination is indicated for all children and susceptible adults, such as child care workers. Revaccination should be considered for patients who originally received only a single dose of the vaccine, particularly students entering college, health care workers, and individuals traveling to endemic areas. A third prophylactic dose reduced the incidence of outbreaks of clinical mumps on college campuses by 78%.
