With less than one week to go in Nunavut's mass flu vaccination program, health officials say more than 40 per cent of the territory's residents have received the shot.

About 13,000 Nunavummiut have rolled up their sleeves for the H1N1 and seasonal flu shots since Nunavut began delivering the vaccine to all communities on Nov. 1.

The immunization program wraps up on Nov. 16. Nurses are in the remote communities of Chesterfield Inlet and Coral Harbour on Thursday, and will be in Kugluktuk on Friday.

Nunavut has ordered enough of the H1N1 vaccine to treat 75 per cent of the population.

The territory experienced a large outbreak of H1N1 cases in the spring but health officials say infection rates so far this fall have been low.
