This five-year-old was born without an immune system and has lived in a sterile germ-free environment for more than half of his short life.

Seth Lane, otherwise known as "Bubble Boy," is in need of a second bone marrow transplant after being born without an immune system. On March 27, his parents are asking everyone to wear yellow and post to social media with #wearyellowforseth. Hopefully the pictures will give him the strength to keep going, according to his mother.
