February 15 is the deadline for school children to be up to date in Oregon on required vaccinations.  Daron Ryan of the Hood River County Health Department says letters will go out to families at the start of February, but she encourages people not to wait to ensure their children are not excluded from classes after February 15.  Ryan says there are no new vaccinations this year on the list required for attendance at Oregon public schools, but letters sent to parents will outline which vaccinations a child needs.
