August not only marks the beginning of school in Kentucky, but also National Immunization Awareness Month, highlighting the importance and benefits of immunizations. Protection received from childhood vaccines decreases over time. Preteens, teens and adults may need to be revaccinated, even if they were completely vaccinated as children. For more information about immunizations, contact the Kentucky Department for Public Health’s Immunization Program at (502) 564-4478 or your local health department or healthcare provider.
