Michael Gorbous, a 16-year-old seen here in an undated Facebook photo, died of H1N1, his family said.

Health officials are blaming H1N1 for the death of a Calgary teenager who had no underlying conditions.

The boy died on Tuesday, bringing the total number of people in Alberta who have died of the swine flu virus since April to 65. Another 1,255 have been hospitalized.

The boy's case is unusual since the majority of people who have died or have been hospitalized had known underlying conditions. Also, the median age among those who have died is 48 years old.

Health officials aren't naming the boy. However Fay Gorbous told CBC News her 16-year-old grandson Michael died from the virus on Tuesday. The family is asking for privacy at this time, she said.

One friend wrote on a Facebook tribute page that Michael won't be forgotten.

"Anyone that knows him would know that he is a great guy and an amazing person to hang out with…He was a legend."

Father urged Albertans to get the shot

Last month, the boy's father spoke to the Calgary Herald about his son, who was at the time in a medically induced coma with pneumonia in both lungs. Kris Gorbous urged people to get the H1N1 vaccination. His son became ill with the virus a few days before the vaccine was available in Alberta.

"I hear a lot of people still questioning if they should get a shot or not. I bring up Michael's case right away," Kris Gorbous told the Herald in late November. "It's imperative that people get the shot."

More than 1 million Albertans have gotten the H1N1 vaccination.

People who have not been vaccinated should get the shot as soon as possible, said Dr. Judy MacDonald, deputy medical officer of health for Alberta Health Services.

"It's a sad situation and our condolences certainly go out to friends and family of this individual. It is a reminder though that influenza is with us. H1N1 activity is lower than it was earlier, but it is still happening," she said.

Alberta's drop-in vaccination clinics for H1N1 will all close before Christmas. Albertans should be able to get the vaccine through doctors and pharmacies instead.
