Saskatchewan health officials say more groups are being added to the priority list for swine flu vaccinations, but individual health regions remain in charge of screening people for the shots.

The new groups, announced Tuesday, include anyone — of any age — with an underlying health condition, and students in grades 7 to 12.

"This will roll out at different rates by regional health authorities depending on the supply of vaccine," announced Dr. Saqib Shahab, Saskatchewan's deputy chief medical health officer.

Saskatchewan said the province had received another 59,000 doses of H1N1 vaccine, raising the total to 320,400.

The province estimates about one-third of the population will have been immunized, once the new batch of vaccine is used.

"The clinics have been operating smoothly and swiftly," Dr. Moira McKinnon, Saskatchewan's chief medical health officer, added. "This has enabled us to move forward to add risk groups more quickly."
