Health officials will decide by Dec. 4 whether to continue with H1N1 immunization clinics in Winnipeg, where lineups for shots have dropped off.

Health officials will decide soon whether to continue mass immunization clinics for H1N1 flu in Winnipeg.

As of 3 p.m. on Wednesday, 186,764 people had received a vaccination in one of Winnipeg's 12 clinics since the campaign started Oct. 26. Health officials will make a decision by Dec. 4 on whether to continue the campaign using the mass clinics.

Dr. Sande Harlos, the medical officer of health for the Winnipeg Regional Health Authority, said the people who have been immunized represent about 27 per cent of the city's population.

She would like to see the number closer to 40 or 50 per cent by the time the campaign ends.

"We've got a lot of flu season ahead of us and we know that even once we get through what we're in now, which is a second wave [of the H1N1 virus], that the transmission will continue unless we have enough people immune," she said.

In total across the province, about 300,000 people have been vaccinated.

But the numbers showing up at clinics have dropped significantly. In Winnipeg, where 13,000 to 16,000 were being vaccinated daily during the peak of the campaign, just 3,589 got the shot on Wednesday as of mid-afternoon.

For those who haven't been immunized, now would be a good time to visit a clinic, Harlos said.

The health authority is looking at strategies for getting the shot to anyone who still wants it, including making it available in doctors' offices should the clinics close.

The immunization clinics run Monday to Thursday, from 9:30 a.m. to 8 p.m., and Friday, from 9:30 a.m. to 4 p.m. Locations are listed on the map below.
