According to Arkansas Children's Hospital, the first step a concerned parent should take is to check immunization records. For children younger than 6, one dose of the MMR vaccine between 12-15 months followed by a second dose between the ages of 4-6 will be 88 percent effective in preventing mumps. Children 7-18 years old who were not previously vaccinated, should receive one dose of the MMRV vaccine followed by a second dose four weeks later.
