SASKATCHEWAN (CBC) - The lineup started before dawn on Tuesday at a Longueuil arena on Montreal's South Shore, where dozens of Quebecers camped out some with their children in tow to get the swine flu vaccine.

It's the second day a predawn queue formed at the makeshift clinic, where the wait on Monday was as long as eight hours, despite diligent work by health professionals administering H1N1 influenza vaccines non-stop.

Complaints about Quebec's mass vaccination program against the swine flu continue to swell as Montreal falls behind other cities in terms of getting people inoculated.

In some parts of the province, the inoculation campaign has progressed to at-risk people including pregnant women, young children and the chronically ill.

But Montreal is a bit behind schedule, Quebec Health Minister Yves Bolduc said in an interview with CBC Radio's Daybreak on Tuesday morning.

Bolduc said he understands peoples' concerns but cautioned that panic is not the answer.

The best strategy to protect public health is to follow the priority list for vaccination, he said.

"For the moment, the experts suggest who needs the vaccine sooner," he said in a telephone interview.

"We have to respect that if we want to save more lives. Everyone wants to be vaccinated sooner, but we don't have a choice at this moment."

Bolduc, who got his shot last week, said his wife and teenage son have yet to be vaccinated, so he understands parents' concerns about their own children.

Bolduc's office confirmed that Quebec still hasn't administered all the doses it has received since the launch of the federal inoculation campaign.

In an emergency House of Commons session Monday night, Federal Health Minister Leona Aglukkaq insisted there is no shortage of the vaccine and every Canadian who wants the shot will get it by Christmas.

Federal opposition parties criticized the Conservative minority government for how it has handled the H1N1 risk.

GlaxoSmithKline, the Quebec-based manufacturer of the vaccine, was forced to slow down production last week to increase the number of doses without an adjuvant an immune booster in order to accommodate demand for pregnant women.
