A lot of kids in Dallas County won’t be able to go to school today because they never got their required shots.  From the Dallas County Department of Health and Human Services, Zachary Thompson says their lines began forming before 7 a.m. even though clients knew the doors wouldn’t open until 8 a.m.  On Friday, Thompson says their clinics were absolutely swamped with parents bringing their children in for last minute immunizations.  Dallas public schools have made it clear no children will be permitted to attend class this year until their shots are up-to-date.
