Thousands of people are begging a drug maker to allow a young cancer patient to get an unapproved medication. 

The email and social media campaign began after the family of seven-year-old Josh Hardy urged supporters on Facebook to pressure the company to provide the antiviral drug. 

Hardy suffers from a viral infection he developed after a bone-marrow transplant.  

The first-grader from Fredericksburg, Virginia has beat cancer four times since he was nine months old. 

The North Carolina-based drug company Chimerix is refusing to allow the "compassionate use" of the drug, saying that providing it could "very likely place the entire development program" for the drug at risk. The drug that could save the boy is in clinical trials.
