It’s that time of summer for parents to start thinking about getting their kids’ back-to-school vaccines. Students heading into transitional kindergarten, kindergarten and seventh grade need to be vaccinated, or in the process of being vaccinated, against measles, mumps, whooping cough and other diseases. Children in child care settings must also be immunized. In the rare instance when a child has a compromised immune system, that child’s physician can provide a medical exemption. During the 2016-17 school year, the prevalence of fully vaccinated Humboldt County kindergarteners increased 5 percent from the year before, and the upward trend continued during the 2017-18 school year, increasing 2 percent from the previous year. For more information about immunizations, contact the Public Health Clinic at 707-268-2108.
