Warren County students entering seventh grade who haven’t submitted proof of immunization required by state law by this Monday will no longer be permitted to attend school and will be marked with an unexcused absence.The school system sent out a letter advising parents or guardians of the requirements on Oct. 13 but there are still a number of students whose parents haven’t provided the required documentation, according to health services director Sonja Walker, RN.The letter stated, in part:Children entering seventh grade must show proof of the following immunizations:• Tetanus-diphtheria-pertussis booster (Tdap).• Varicella (Chicken-Pox) booster or verification of history of disease.• These vaccinations must be recorded on the official Tennessee Department of Health certificate of Immunization which is available from your child’s health care provider or local health department.• If proof of immunizations is not provided by Nov. 7, 2011, your child will not be permitted to attend school and will be marked with an unexcused absence.“It’s a state law that we have proof to attend school,” Walker said, noting the majority of the students lacking proof are at the seventh-grade level. “We’ve never really had this problem in the past, but because seventh grade has added those two boosters, that seems to be the target area, but it is county-wide.”In some cases Walker says the children may actually have received the immunizations but the paperwork hasn’t been submitted. If so, the proof must be obtained and turned in by the Nov. 7 deadline.If the children haven’t received their shots, Walker says parents can contact their health care providers, or contact the local Health Department, to make appointments to receive these required vaccinations.
