People in Saskatoon who qualify to get the flu shot faced long lineups as hundreds waited for the vaccine Saturday. 

The province announced it would be limiting the influenza vaccine to those most at risk because of a shortage of doses, allowing only children between six months and five years of age, and pregnant women to get the shot.

Regan Toni waited in line to get her son vaccinated.

"I was meaning to get one for him and then just never got around to it," Toni said. "So it seems like this might be our last shot. I don't really care if I get it that much. I just wanted to get it for him so that's what matters."

Regina ran out of flu injections over the weekend, but not before vaccinating 700 more people.

The province is expects 12,000 nasal spray vaccines to arrive early this week. 

However, the nasal spray vaccines cannot be taken by pregnant women, children under two-years-old and those with compromised immune systems.
