There have been recent changes to the Kentucky Immunization Regulations. These include one new age-specific immunization and one booster dose requirement effective July 1, 2018. All children are required to have a current certificate of immunization status to attend child care, preschool, and public or private primary or secondary school. Talk to your physician or the local health department to insure that your child is up to date on all immunizations. Learn more: Immunization Update 2017.
