Parents of soon-to-be seventh-grade students have the rest of the summer to make sure their children comply with the new state immunization law. Beginning this upcoming school year, all entering seventh-graders are required to have the meningitis vaccine and the Tdap booster shot for tetanus, diphtheria and pertussis. “We’ve had an increase in the number of pertussis cases over the years (across the state),” said Mamie Coker, health services coordinator for the Hall County School District.
