Jen Fisher can do only so much to keep her son safe from the types of infections that children can encounter at school. The rest, she said, is up to other students and parents in their hometown of Franklin, Tennessee.
Fisher’s son Raleigh, 12, lives with a congenital heart condition, which has left him with a weakened immune system. For his protection, Raleigh has received all the recommended vaccines for a child his age. But even with his vaccinations, a virus that might only sideline another child could sicken him and land him in the emergency room, Fisher said.
