LEE COUNTY, Fla. - It's almost back-to-school for Lee County students, which translates to another dreaded trip to the doctor for student's annual shots.

Lee County Health Department is reminding parents to get kids checked out now, to prevent them from being turned away from classrooms on the first day of school on Monday.

"Sometimes, the children don't always have everything they need to enter the school. So they are excluded from school until they met the requirements," said Lee County School Health Coordinator Tammy Moser.

There are two main changes for immunization requirements this school year. The first involves the varicella, or chicken pox, vaccine. Kindergarten through second grade students are now required to have the immunization. Previously, the vaccine was only required for kindergarten and first graders. The tetanus-diphtheria-pertussis (TDAP) vaccine is also being extended this school year to include eighth graders. Health Department officials say both changes only apply to children new to the state, or entering the grade as a remedial student.

As for the annual flu frenzy, students can celebrate only one painful pinch this go-round.

"It is combined this year, so it will be H1N1, as well as the regular seasonal flu in one vaccine," Moser said Tuesday.

Lee County Health Department is offering all required vaccinations free of charge to students under the age of 19. Already, the free clinic is seeing lines out the door.

"They told me it would be a two hour wait, and I pulled a number and had to fill out papers," said Barbra Kondzich, who's trying to get her two boys up-to-date on vaccinations.
