Return to pre-pandemic normalcy not yet on the horizon for many immunocompromised Americans

For some of the 7 million immunocompromised Americans, COVID-19 has been "devastating."

When coronavirus shut down the nation nearly two years ago, 7-year-old Xiomara Hung and her family were quick to retreat to their Maryland home in an effort to help curb the spread of the virus and avoid any potential infection.

Like many children across the country, Xiomara and her brother were forced to trade their backpacks for laptops as the virus forced schools online.

However, unlike most students, who are now back to in-person schooling, Xiomara, who was born with a number of medical conditions affecting her airway, lungs, heart and kidneys, has not yet been able to return. Because she is immunocompromised, her parents have been faced with the difficult decision to keep her away from her peers in virtual schooling while the virus is still circulating.

"It's been really hard," Xiomara's mother, Elena Hung, told ABC News. "But in a way, it wasn't a hard decision. Do we keep her safe and alive, or do we send her to school? The goal is absolutely her to go to school, but I have to weigh that against her safety. There's no point in going to school, if she's going to get sick, and she might end up in the hospital."
