District officials say both students only had one of their rounds of shots, but children aren't the only ones contracting the disease.

Many of those people had already had both immunizations.

Sharon Watson with the Kansas Department of Health and Environment says the Center for Disease Control is looking into why so many people between 20 and 30 are who've had their immunizations are getting mumps, "That's something the CDC and others will be looking into to see if there’s something going on with the vaccine at this time we don't have any information indicating that's the case but we'll be looking into that."
