JOHNSON CITY, Tenn. -

Doctor's offices are starting to get booked with appointments and that's because parents are rushing to make sure their kids the vaccinations they need.

Janie Synder with the Johnson City Schools says those shots could save a child's life. "For their own personal safety to be free of childhood diseases, for the safety of other students to be free of childhood diseases, so that we do not have epidemics," says Janie.

Children who are going to school in the Johnson City School system for the first time must have 4 Polio and 4 DPT, which is Diphtheria, Pertussis, and Tetanus as well as other shots. "2 MMR for your Measles, Mumps, and Rubella, and three hepatitis. Your hepatitis A, your Hepatitis B, two Varicella, which are your chickenpox," said Snyder.

If your child is going into seventh grade, we learned they also need to update their D-tap booster.

Pediatrician Dr. Landon Combs says these vaccinations can make a difference. "You're protecting your child against something which could possibly kill them or cause them to have great difficulty later in life," Dr. Combs stated.

Combs says some of these diseases are making a comeback because people are not getting vaccinated. "People stopped doing Diphtheria, Tetanus, and Pertussis in Europe. They had a big up swinging in Whooping Cough and things of that nature," Dr. Combs said.   

News 5 learned if your child does not have the vaccinations or an appointment to get them before school starts, the school will set a timeline for when they need to be completed.

Janie says they will work parents if there is some type of conflict. "If a health reason then the physician can work with the family on that and let us know if there is a reason because of religious preference then there are certain steps we follow there," says Snyder.

We learned the Johnson City Schools follow state regulations of Tennessee when it comes to vaccinations.

Those also follow regulations set by the center for disease control.
