EDMONTON - Alberta Health officials confirmed Friday they will expand their swine flu vaccination program to inoculate more children at risk.

As of Tuesday, two caregivers for each child under six months will be allowed to get the shots, said Andre Corriveau, the province's chief medical health officer.

Children that young can't safely get the shots themselves, he said, so the help will go to the two closest caregivers.

Also, children under 10 years old with medical conditions that put them at high risk for H1N1 will also be eligible.

Corriveau said officials wish they could inoculate more.

"It it was up to us we would be providing vaccine to whoever wants it, but we have to face reality," Corriveau told a news conference.

He said an estimated 56,000 peoplewill qualify for the expanded program.

Pregnant women and children under five but older than six months are already eligible.

Gerry Predy, Alberta's senior medical health officer, said lineups have moved quickly at the vaccination centres.

Predy said they've delivered 35,000 doses to children under five.

"We view that as quite a success," he said.

The clinics reopened Thursday after being closed for four days to reorganize. Staff had been overwhelmed with long lineups and vaccine reserves became dangerously low after the Alberta government told everyone, not just those at risk, to get the shots.

Also Friday, it was confirmed two more people died of H1N1, bringing the provincial death toll to 20.

Predy said the latest victims were two elderly Edmonton men with pre-existing conditions that made them susceptible to the swine flu.
