Measles Health Alert

Grunt Doc alerts :Three cases of measles in Houston. One patient visited five different hospitals/doctors before measles was diagnosed.

I wonder if the MMR needs to be updated often. This post purports to answer your questions, but it didn’t tell me if the boys would need a booster. It only mentions college kids possibly getting one.

I know the kids had MMR when they were 5 and 6 (respectively). I hope that was sufficient.
