Kael Morrison, boy in heart-wrenching SickKids ad, makes history

Kael Morrison is a rambunctious nine-year-old boy. But until very recently, that wasn't the case.

Many people might recognize Kael froma gut-wrenchingad for theSickKidsFoundation.

In the ad,the boy, who was seven at the time, becomes flustered during a shadow boxing exercise with his physiotherapist Ryan Ireland. He pauses, wipes aside tears and perseveres to complete the exercise by punching Ireland's hands, his fists clenched around tiny dumbbells.

Kael was diagnosed at age five with Stat-1 Mutation, a rare immune-deficiency disorder. Iteffectively decimated his immune system. It was possible he would not live past 12 years old.

There are approximately 15 to 20 people with STAT-1 deficiency in Canada, mostly children, according to SickKids Hospital. Some 100 children are affected worldwide.

Doctors said Kael's best chance of survival was to undergo a bone marrow transplant.

Luckily, his four-year-old brother Eamonwas a match. Eamondidn't hesitate to give his big brother some of his "soldiers," as their mother Emily Morrison said.

"There was no question in his mind," she said of her younger son.

A year spent in hospital

Kael underwent the bone marrow transplant in Nov. 2013.The road to recoverywas a long one with complications from the operationkeeping him in hospital for a full year.

He spent six months in isolation due to the threat of infection and wasn't allowed skin-to-skin contact with anyone, including his mother. Visitors and nurses had to wear protective gear just to sit in the same room with him.

For the little boy, every day was "boring." For his mother, this period was particularly difficult, she said.

"When we were able to lift that restriction,you can't even describe it, being able to touch him skin-to-skin and give him a kiss and tuck him in bed. It was pretty awesome."

Returning to the hospital gave Morrison the chance to put Kael's progress into perspective.

"There are days we had to talk to him about just getting out of bed," she recalled. "Now it's 'slow down, don't run around the house with your boots on.'"
