Vaccines a challenge for homebound BrightStar is not under contract with the state to do homebound vaccinations even though it meets state credentials to provide the shots and was approved in January to do so, said Nimnuan, the agency's vice president. Like many seniors, the homebound may not have grown children who can get them signed up for the shots or they don’t have caretakers who can handle the arrangements, she said. More so, it's not possible for the homebound to sit in a car waiting for a shot in a county-run drive-up clinic or stand in line, she said.
