The family of a five-year-old from Corby who has spent much of his life in hospital face an anxious wait over the next few months to see if a bone marrow transplant will be a success.
Seth Lane was born with a rare condition which means he has no immune system.
As a result, he spends almost all of his time in the same room, nicknamed a ‘bubble’, at the Great North Children’s Hospital in Newcastle, with his mum and dad Leanne and Nik.
Mr Lane said: “Seth has been in hospital for a long time and as you can imagine he gets a bit bored.
“He loves Fireman Sam, Paw Patrol and anything yellow, so we decided to make a video asking people to wear yellow for him on Friday, March 27, and post pictures so he could see them.
“We thought only family and friends would be interested but the video has been viewed more than two million times and we are getting messages from all over the world.”
Seth was diagnosed with his condition when he was six months old, and had a bone marrow transplant at Great Ormond Street Hospital.
But only a couple of years later, soon after the Fireman Sam-loving youngster started making friends in the reception class at Beanfield Primary School, he was forced to return to hospital after complications began to arise.
Since January, he has been living at the hospital permanently and has been unable to see his little brother Hugo, aged five months, apart from very brief visits.
The room he lives in is ultra-hygenic and anyone, including his family, who spends time with him has to wash and scrub before they can enter.

Staff keep the room scrupulously clean and there is also a filtration system to keep the air free from germs.
His dad said if anyone is suffering from even a minor illness like a cold, or if they are felling run-down and worried they might be ill, they are not allowed to spend time with Seth.
The youngster will be receiving a bone marrow transplant from his dad Nik in May, and if that is a success the family is hoping to return home in the summer.
However, they will face an anxious wait in the months after the operation to see if the transplant has worked.
