LAS VEGAS -- A Las Vegas Valley mother is grieving after her 6-year-old died from H1N1.

This comes as the Southern Nevada Health District decided to expand its H1N1 at-risk priority groups to include adults 19 to 64 with pre-existing medical conditions.

The mother of Daejon Meadows said he was just days away from getting his H1N1 vaccination when he came down with the flu. Three weeks later, he was dead.

“He was very loving, a nice person to be around, sweetest kid,” said mother Shannon Wilson.

Her son is just one of the latest victims of H1N1 in southern Nevada, and he was the youngest. Daejon died on Thursday. He had sickle cell anemia, which put him at greater risk.

“His immune system was weak, and he couldn't fight it,” said grandmother Dorothy Barnes.

Daejon's grandmother said she thinks he likely got the virus while at school. On Tuesday, at a fundraiser walkathon at Martin Luther King and Carey, she fought back the tears describing her grandson’s last days.

“It’s just devastating. It’s hard to see that. You sit up in the ICU seeing your grandson laying there,” Barnes said.

Dozens gathered to walk in Daejon’s memory, trying to raise $2,000 for his funeral. Wilson said she wonders if an H1N1 shot had been available sooner if her son might still be alive.

“He was supposed to. He couldn’t get the mist, so I had to wait for the shot to become available for him,” Wilson said. “It was supposed to be that Saturday, and he was admitted the day before.”

And during the three weeks Daejon was in the hospital, his family described the experience as terrifying.

“Lying there with the blood coming from a tube trying to save his life … they did all they could,” Barnes said.

Daejon will be buried this Saturday. His mother said she was hopeful that they would raise enough money from the fundraiser to pay for the funeral.
