Florida law requires all students have a Tdap (tetanus-diphtheria-pertussis) immunization before entering 7th grade. If you do not have a doctor or healthcare provider, the Florida Department of Health in Clay County offers FREE immunizations to students. For more information please call (904) 529-2800. Help your child have a smooth transition to 7th grade. Immunize now and return proof of Tdap shot (on the DH 680 form) to your child's elementary school prior to the end of school. Be Ready!
