Mumps primarily affects school-aged children. The risk of exposure to mumps outside the United States may be high.
Few countries use mumps vaccine, so mumps remains a common disease in many countries of the world.
Vaccine Mumps vaccine contains live attenuated mumps virus. MMR vaccine is recommended whenever one or more of the individual components is indicated. Immunity to mumps is of particular importance for children approaching puberty, and for adolescents and adults, particularly males, who have not had mumps. Most adults born before 1957 are likely to have been infected naturally and generally may be considered immune, even if they did not have clinically recognizable disease. However, mumps or MMR vaccine may be given to older persons if there is reason to believe they may be susceptible.
