As summer break comes to a close, health officials are reminding parents to make sure their kids have their immunizations up to date, or they'll be left out of school.


"We're just encouraging parents to find out if they're children's immunizations are up to date, and not to wait until the last minute," said Lydia Sandoval with the Florida Health Department in Miami-Dade.


That is because students without the proper documentation will not be allowed to attend school.


Students new to the school system, including kindergartners, need to have their forms in before the first day of school.


Students entering seventh grade are required to get booster shots.


All South Florida counties offer free immunizations at a variety of locations.
