An Atlanta lawyer is asking the Georgia appellate courts to put the brakes on a train of decisions nationwide that have stymied suits over alleged adverse effects of vaccines.

The case argued Tuesday at the Supreme Court of Georgia was brought by an Atlanta couple who say their 10-year-old son suffered neurological problems as a result of childhood vaccines. The vaccine manufacturer defendants argue that the couple’s claims cannot succeed because of a federal law that set up a system of compensation outside of the regular court system for vaccine injuries.
