Vaccinations carry risks, but so does not vaccinating. If you just want to talk percentages, what is the chance that you will have an unusual or adverse reaction to a vaccination vs. what is the chance that you will contract and have an adverse reaction to the illness? Even on those terms it seems worth it to vaccinate against MMR. Those vaccines have been around for a long time, they are effective, and they are safe. They are certainly much safer than measles, mumps, and rubella. It used to be that you could avoid the risk of vaccination entirely by assuming that everyone else around you would vaccinate. That's no longer a good assumption. Plus, there is the compounding factor that by not vaccinating, these people are facilitating harm to others. Government is all about balancing benefit and risk as a whole.
